Haynes-Griffin Radio Service Inc.
41 West 43rd Street
New York City, New York

In 1922, Haynes opened the Haynes Radio Shop, a small store on Lexington Ave. in New York City. Shortly after, a Mr. Griffin joined the firm to assume the position of President, as his expertise was in advertising and merchandising, whereas Haynes was the technical expert.

The company then purchased the Lexington Radio and Electric Co., along with the stock and entire personnel. This merger made the Haynes-Griffin Radio Service Co. the oldest and best in New York City, with 4,000 square feet of space devoted to the sale and repair of radio apparatus. The firm, located on 41 West 43rd St., advertised itself as "New York's Largest Radio Store."

Artemis J. Haynes had been in the vanguard of radio since 1917 when he was in the Naval Reserve and attended the Brooklyn Navy Yard Radio School. He became an instructor of the first principles of radio at Yale University. In addition, he worked for the De Forest Radio Co. as an engineer, and during 1920-1921, he operated the De Forest experimental station at Highbridge (2XG), along with Robert F. Gowan at 2XX.
