A hundred years ago today, radio amateurs were making their way to the Windy City for the first national convention of the American Radio Relay League (ARRL), held at Chicago’s elegant Edgewater Beach Hotel. The occasion was a momentous one, and the following account was carried in the August 29, 1921, issue of the Washington Herald under the heading “Scientific Notes and Comment”:
FIRST NATIONAL RADIO CONVENTION THIS WEEK
From 2000 to 3000 radio operators and engineers from all parts of the country are expected to attend the first national convention and radio show of the American Radio Relay League in Chicago, August 30 to September 3.
The program Includes papers and entertainments of a novel character, and the latest improvements in commercial and experimental wireless apparatus will be shown at the exhibition.
Secretary of Commerce Hoover [whose son, W6ZH, would go on to become the organization’s President in 1962] will send a radio message to the convention, which will be transmitted from the Postoffice radio station In Washington to Cincinnati and then relayed to Chicago, where it will be received in code in a loud-speaking telephone. Each radio enthusiast, in true operator style, will take down in writing the greeting as it is received. Secretary Hoover is the Cabinet officer who administers the government radio in this country through the Department of Commerce Bureau of Navigation.
Rear Admiral W. H. G. Bullard, in charge of wireless for the navy, will be present at the convention.
Several Washington radio men expect to attend the convention as representatives of the local radio club.
The main exhibition hall, located at the nearby Broadway Armory is shown in this grainy photo, the caption of which notes that most attendees were at dinner when the picture was taken.
An extensive writeup of the event can be found in the October 1921 issue of QST, and there is additional material at the ARRL website.
QST reported that the delegates in attendance greeted Secretary Hoover’s radiotelegraph message with cheers:
The Department of Commerce is by the authority of Congress, the legal Patron Saint of the Amateur Wireless Operators. Outside of its coldly legal relations the Department wishes to be helpful in encouraging this very important movement. I am asking Mr. Terrell, the head of our Radio Division, to go to Chicago to learn from you where the Department can be of service.
–Herbert Hoover
