Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
Vintage photos of:
1924. "The latest in radio development which has been perfected by Mr. H.P. O'Reilly of Washington, D.C." Which seems to incorporate a "Telegraphone," the early wire recorder alluded to on the wall. Never miss another radio program again! Harris & Ewing Collection glass negative. View full size.
This early prototype "Go-Ogle Auto-Rig" was operated by a driver and a lensman who fed motion picture film into the 360-degree camera at the rate of 90 feet per minute. After being conveyed through the mobile developing tank, footage was viewed using a stereopticon indexed to a telephone directory.
March 26, 1923. Washington, D.C. "Test car, Bureau of Standards." See above for details. National Photo Company Collection glass negative. View full size.
1924. Washington, D.C. "In recognition of his having conducted the most successful radio exhibition in the U.S., Alfred Stern, director of Washington's first radio exposition, was presented with this elaborate loop antenna by Dr. J. Harris Rogers, famous inventor. It is estimated that 50,000 persons attended this exhibition." Harris & Ewing glass negative. View full size.
Washington, D.C., circa 1922. "Coin-operated radio in barbershop." Seen earlier outdoors. A closeup of the instructions for the set, provided by American Field Glass Service (which also supplied, we would guess, coin-operated binoculars and telescopes) can be seen here.
