Joseph Priestley is on the Move Again

Bronze Sculpture of Joseph Priestley, Leeds, England. Walter Harding, sculptor, 1903

In an article in the Birmingham Mail it has been reported that the bronze statue of Joseph Priestley in Chamberlain Square is on the move.  The statue has been removed from its plinth and transported into storage at the Birmingham Museums Trust Collection Centre ahead of the demolition of the Central Library and the start of reconstruction of the area around the Square.  The statue of James Watt was also removed and the statue of Thomas Atwood will also be removed in a similar manner.
They will all be returned to the Square when the construction work is completed.

Both Watt and Priestley resided in Birmingham during the early days of of the Industrial Revolution and were members of the Lunar Society.  Priestley, a clergyman, scientist, educator, and social activist is best known for his discovery of Oxygen.  James Watt and Matthew Boulton are credited with the development of the steam engine.

The Joseph Priestley Statue was originally located in Victoria Square, then called Council House Square, but was later move to Chamberlain Square and recast in bronze due to irreparable weather erosion to the original marble.

On the Elderly in the Early Days of Photography and Motion Pictures

George Washington was born in 1732.  When he died in December of 1799, there were no photographic images of him ever taken because the technology of the photographic process had not been discovered yet.  If you want to "see" what George Washington really looked like, you are limited to viewing interpretive paintings, drawings and engravings of him.  Perhaps that is why different pictures of him look like they are not of the same person.

Recently, I was rummaging around and found some old 16mm home movies that my father took in the 1930s.  It had some great shots of his father-in-law.  I was excited to retrieve this footage of my maternal grandfather and I'm going to have it digitized so that I can preserve it and pass it on to my grandson. After all, this is footage of his great-great-grandfather and it ties in well with the genesis of the search for information on my grandparents which I have been collecting since I posted a piece called Touchstones of Time on this blog.

Unless you just happened to have read that post and remembered a lot of the details, I wouldn't expect you to remember that my maternal grandfather was actually born in 1862.  So, in short, I have a motion picture of a person who was born in 1862.

The question I posed to myself is what is the earliest birthdate of a living person (i.e., living at the time of the shooting of the images) whose image is captured on film?  And, of course, the related question, what is the earliest birthdate of a living person who is captured in a photograph?

I have no doubt that there are motion pictures that exist that are of individuals far older than my grandfather.  As a candidate for the earliest birthdate of an individual captured in a photographic image I immediately thought of an image I have seen of Dolley Madison taken on

Dolley Madison, July 4, 1848, age 80
July 4, 1848, who was 80 years old at the time.  She was born on May 20, 1768, almost 250 years ago.  Dolley Madison, of course, was the wife of the fourth President of the United States, James Madison.
Dolley Madison, 1848 daguerreotype by Mathew Brady
A slightly older John Quincy Adams, born on July 11, 1767, was the sixth President of the United States and was captured in the photograph below.
John Quincy Adams, 1843

And, a still older individual, Samuel Wilson, who was born September 13, 1766, was a resident of Troy, New York, and is recognized as the origin of the term "Uncle Sam". The picture below was taken in 1843.  He was 77 years old when the picture was taken.
Uncle Sam Wilson, 1843

Daguerreotypy developed by the French painter Louis-Jacques-Mande Daguerre, was the first publicly announced photographic process ever developed, in 1839, some nine years previous to the shooting of the image of Dolley Madison above.  

On a purely speculative basis I am presuming that the oldest person in a photographic image was shot shortly after the technology was developed in 1839 and that person would have been in their late 80s.
That would put their birthdate somewhere around the beginning of the 1750s.  To put this in perspective, it would have to have been a person born about a decade after George Washington.

The French physiologist Etienne-Jules Marey took the first series of photographs with a single instrument in 1882 with a camera shaped like a rifle that recorded 12 successive photographs per second.   However, the world's oldest photographic moving picture sequence is by the French photographer Felix Nadar who created his revolving portrait in 1865.  Thomas Edison is credited with having taken the first true motion picture in 1889, but the image's quality is so poor that the identity of the individual who was the subject in the movie is not discernable.

Again, on a purely speculative basis I am presuming that the oldest person in a motion picture sequence was shot in the early 1890s and that the person could have been in their late 80s.  That would put their birthdate somewhere just after the beginning of the 19th century; probably someone around Abraham Lincoln's date of birth. 

Here is a Youtube sequence of old motion picture cuts from New York City, the oldest being from 1896. If any readers would like to nominate a picture or motion picture that would be a candidate for the oldest person in each category we would like to hear from you.

Is a Hyperloop Pneumatic Tube for the Transport of People and Goods Really Possible?

In 1897 the United States Post Office started to install pneumatic tubes in a 
number of metropolitan areas in order to expedite the delivery of the mail. 
By 1898 the tubes were in operation.   

Robin Pogrebin, in an article in the New York Times on May 7, 2001, wrote a
fascinating piece on the history of the pneumatic tube mail system.  In the article 
he highlighted some of the features of the system.  The system was thoroughly 
modern, some might even say high-tech.  It was like subterranean internet for 
priority and first-class mail powered by air pressure. Pneumatic tubes similar to 
these are still used in some banks, and other specialty areas.  I even saw some at
Home Depot not too long ago.

The mail tubes were installed in the cities of Boston, Philadelphia, Chicago, St. 
Louis, and New York.  In Manhattan, they extended about 27 miles, from the old 
Custom House in Battery Park to Harlem and back through Times Square, Grand 
Central Terminal and the main post office near Pennsylvania Station. In the 
picture above at the at the City Hall station, the mail also went in a pneumatic tube 
over the Brooklyn Bridge to the general post office in Brooklyn. 

The system used pressurized air to move a mail canister through an underground 
eight-inch cast-iron pipe.  In New York City, two pipes were used along each 
route, one for sending, the other for receiving.  The pipes were buried 4 to 12 feet 
underground, though in some places the tubes were placed within subway tunnels.  
Improvements in the speed of the motor-wagon and its successor, the automobile, 
signaled the end of the pneumatic tube.  However, the tube system remained in 
operation in New York City until December 1, 1953.

battery compartment at the back and 
air bearing skis at the bottom.

The modern day equivalent to the pneumatic air tube of the postal service 
of the late 19th century might arguably be the hyperloop (see the
illustration above), a conceptual high-speed transportation system proposed 
by Elon Musk in 2013 as a means of efficiently transporting people and 
goods quickly over large distances.  The Hyperloop would incorporate 
reduced pressure tubes in which pressurized capsules would ride on an air 
cushion driven by linear induction motors and air compressors.

While the hyperloop has been roundly criticized as a "pipe dream."  

Some elements in the Musk conception of the technology to realize the 
hyperloop would utilize newer technological components such as a linear 
induction motor, history shows us that the general concept is far from new, 
and far from impractical.

Of the Invention of Telescopes and Microscopes, with their First Improvements

Screen Shot 2015-08-08 at 11.10.58 AM.png

I happened to run across an article by Joseph Priestley  [Priestley, Joseph, LL.D, F.R.S., Of the Invention of Telescopes and Microscopes, with their First Improvements,The Literary and Biographical Magazine and British Review, vol.10 (June,1793): pp. 407-11.].

What I found so interesting with this article was that I could not find it listed in any of the standard bibliographies of his works; not even in the on-line Wikipedia bibliography on Joseph Priestley, which, importantly, is the most up to date (I have subsequently corrected that situation), nor in Robert Schofield book which is considered the authoritative biography on Priestley with an excellent bibliography.  It seems rather odd that a person with such a distinguished career and elaborate corpus of works as Priestley would have a publication missing from his bibliography for more than 210 years after his death, and 221 years after he wrote the article.  

I note, however, that while there was a section on the very subject of the article with the exact same title I found in his book: The History and Present State of Discoveries Relating to Vision, Light, and Colours, London: Printed for J. Johnson, 1772,pp.55-81, there is enough of a difference between the two works that this work should have been recorded as part of his bibliographical legacy. Further, it should be noted that there is a full 21 years difference between the publication dates of the book and the journal article. Finally, it is worth noting that it doesn't make any sense to have excluded it, based solely upon the fact that it appeared in such a prominent British publication with his authorship clearly identified.

One final note about the article, versus its content, is that while the title as stated above is what appears at the head of the magazine article, all subsequent pages of the article carry the banner "On the Invention of Telescopes and Microscopes" [emphasis added].

"The More Elaborate our Means of Communication, the Less we Communicate" J. Priestley

I have often seen the quote offered in the title of this post attributed to Joseph Priestley (1733-1894), the famous 18th century British-American polymath who was the first to report the isolation of the gas Oxygen.  It has never sat right with me.  I have studied much about Joseph Priestley's life and it just didn't seem like there was much in the way of "elaborating" communication that had transpired before or during his lifetime other than the invention of movable type and the printing press in the 15th century.  I had often thought that a more probable candidate for the quote was J(ohn). B(oynton). Priestley (1894-1994), the famous twentieth century British novelist and broadcaster.  He was certainly alive during a period of rapid change in communications technology; as a broadcaster was most certainly aware of communications skills; and, as a novelist he could certainly elaborate upon all this.

 I have found two quotations, one is the title of this post and the other, almost identical, which, at first blush, looks identical, “The more we elaborate our means of communication, the less we communicate”.  The second quote has an additional "we" as the third word.   Of the numerous sources I have found they attribute each of these quotations to either J. B. Priestley, or Joseph Priestley (by the way, most are attributed to Joseph Priestley).  Interestingly, though, the quoters are not unanimous on which is attributable to each person. Not one quoter has actually cited the primary source (by primary source, I mean the actual publication by the respective author). I have found it hard to believe that these two people with almost identical names, each uttered almost identical quotes. I also find it hard to believe that I could not find the actual source of the quotation. 

I am proud to announce that, after a considerable search, I have now found the proper attribution and wording for the quote: “The more we elaborate our means of communication, the less we communicate.”  See Baden Eunson, Communicating in the 21st Century, in reference to Priestley’s Paradox.  The source reference for the quote is J.B. Priestley, Thoughts in the Wilderness,   Heinemann, 1957, p. 201. 

And, of course, the photo above is that of the author of the quote, J. B. Priestley.  May he rest in peace.

Joseph Priestley on Public Television

Wed, Aug 19 at 8 pm, PBS
(Check your local PBS station for broadcast times)

Patrick Page as Joseph Priestley                      Patrick Page, Ava Deluca-Verley and Hugo Becker
 as Joseph Priestley, Marie Anne and Antoine Lavoisier

The Mystery of Matter: Search for the Elements is an exciting PBS series about one of the great adventures in the history of science: the long (and continuing) quest to understand what the world is made of—to identify, understand and organize the basic building blocks of matter.

Three hour-long episodes introduce viewers to some of history’s most extraordinary scientists: Joseph Priestley and Antoine Lavoisier, whose discovery of oxygen—and radical interpretation of it—led to the modern science of chemistry; Humphry Davy, who made electricity a powerful new tool in the search for elements; Dmitri Mendeleev, whose Periodic Table brought order to the growing gaggle of elements; Marie Curie, whose groundbreaking research on radioactivity cracked open a window into the atom; Harry Moseley, whose discovery of atomic number redefined the Periodic Table; and Glenn Seaborg, whose discovery of plutonium opened up a whole new realm of elements, still being explored today.

The Mystery of Matter shows us not only what these scientific explorers discovered but also how, using Broadway-caliber actors to reveal the creative process through the scientists’ own words, and conveying their landmark discoveries through re-enactments shot with working replicas of their original lab equipment. Knitting these strands together into a coherent, entertaining whole is host Michael Emerson, a two-time Emmy Award-winning actor.

Mystery of Matter:  Search for the Elements will be shown on PBS on Wednesday, August 19, 2015 from 8PM to 11PM. (3-1 hour shows airing back to back)

The Oldest Tunnel in New York City

There are a variety of types of tunnels that can be built. Primarily they are the cut and fill and the true tunnel.  In the cut and fill method, which is used because it is much cheaper to construct, a trench is dug, the tunnel walls and ceiling are constructed of masonry or other materials, and then the earth is returned to the trench to "bury" the tunnel.  The true tunnel is constructed by literally digging from one end to the other (or, more often, digging from both ends towards the middle). Some true tunnels are dug in dirt, and others through stone. The advantage of stone, many times, is the lack of need for a supporting structure, but the disadvantage, of course, is that the tunnel must be cut from the very strong stone, which makes it much more difficult and time consuming, not to mention the cost.

The oldest true tunnel in NYC for rail traffic, or any kind of traffic, is the Mount Prospect Tunnel in Manhattan, opened in 1837. It now forms the center two tracks of Metro North from 92nd St. to 94th St. under Park Ave. The tunnel north and south of it, and the one-track tunnels on each side of it, were added in 1873-1875, but the Mount Prospect Tunnel was left in place and became part of the larger “Fourth Avenue Improvement”

The following illustration that appeared in the November 14, 1874 issue of the Scientific American shows the ground elevation and other pertinent information on the underground rail line from 42nd St to the Harlem River which was completed in 1875.  Of course, Fourth Avenue, became Park Ave.
In the center frame I have enlarged below you can clearly see that the section between 92nd and 94th Streets is labelled "Rock Tunnel."

Interestingly, the area that the Mount Prospect Tunnel is located is now called the Carnegie Hill area of the upper East side of Manhattan.  That name, Carnegie Hill, became the new name for Mount Prospect after Andrew Carnegie purchased land (1897) and built his residence (1903) at 91st Street and 5th Ave., a few blocks away from the tunnel.

The Atlantic Avenue Tunnel (also referred to as the Cobble Hill Tunnel) in Brooklyn was built in 1844-45 and is touted as the oldest Railway Tunnel in the world, it has been cited that the Mount Prospect Tunnel, while having been built earlier, was originally built for street cars and only converted to be a railway tunnel in the mid 1870s.

Cobble Hill Tunnel

There is a belief that a true tunnel was constructed for the Croton Aqueduct in upper Manhattan which opened in 1842, but that has not been documented as of this writing. Clearly, that tunnel, if it exists, was not for traffic at all, but rather a viaduct for water and appears to be constructed around five years after the Mount Pleasant Tunnel was completed.
