    Typewriter at right is labeled, "International Business Machines Corporation -- Electromatic Typewriters Division." According to "In 1928, when the General Motors Corporation purchased the Northeast Electric Company, the departments manufacturing the Electromatics did not go along in the transfer of ownership, but struck out with Rochester capital behind them to organize a new company under the same name of Electromatic Typewriters, Inc. The first model of Electromatic's new machine was completed on March 4, 1930. In 1933 Electromatic Typewriters became a division of IBM and immediately reaped many benefits from its association with this corporation. IBM's highly skilled engineering, educational and sales departments were instrumental in the continued steady growth of the Electric Typewriter Division."

    Thanks[email protected]! Using some of the information you added I was able to find a similar newspaper photo published in the July 29th, 1934 issue of the Chicago Daily Tribune with the caption: "Typing By Radio. Weather information may be distributed in the future by the federal airways system through the aid of radio typewriters if experiments now underway in the office of the bureau of air commerce of the department of commerce meet with continued success. The radio typewriter developed by Walter S. Lemmon (left), radio engineer is being tested by officials of the bureau." We'll add this info to the catalog record.
