In 2009, the renowned classical music radio station, WQXR — which was the last commercial classical radio station in the New York City area — sold its frequency, and became part of the public radio network at a new frequency and at one tenth its former signal strength. Among WQXR’s founders was former [[Presidents of the Institute of Radio Engineers (IRE)|IRE President]] John Vincent Lawless Hogan. John V. L. Hogan was not only a prolific inventor who presided over some important developments in [[Radio|radio]] and facsimile, he was also a crucial early leader who shaped the [[IRE History 1912-1963|IRE]] — and thus [[IEEE History|IEEE’s]] — institutional history.

John Vincent Lawless Hogan was born in Philadelphia on 14 February 1890 and was raised in New York, where he attended the Horace Mann School. Shortly after graduating in 1908, he began work as an assistant to [[Lee De Forest|Dr. Lee de Forest]], who had just invented the vacuum tube. Hogan spent three years at the Sheffield Scientific School at Yale where earned honors in physics and mathematics and he worked on detectors and circuits. He was awarded several patents for his early work.

Hogan joined the staff of Reginald Fessenden's National Electric Signaling Co. as a telegraph engineer in 1909. Throughout his time with them, he continued to collect patents as he worked to improve the quality of radio transmissions. During World War I, he and his employers applied their talents to equipping American military planes and ships with radio equipment. He remained with National Electric Signaling, through its various name changes, until 1921 when he went into business for himself as a consultant.

During the 1920s he experimented with television, radio and facsimile transmission. In the late 1920s, he was broadcasting a sound program to match a visual one over an experimental frequency, W2XR. People with radio receivers began to pick up his experiments and, appreciating the quality of his transmissions and his choice of music, they asked for more programs. In 1936 Hogan partnered with Elliot Sanger and founded the Interstate Broadcasting Company to operate W2XR as WQXR, meeting the public’s demands. The radio station became known for the high technical quality of its programs.

He was born in Philadelphia, Pennsylvania, U.S.A. on 14 February 1890 and was raised in New York, where he attended the Horace Mann School. As a teenager, he was a [[Amateur Radio|radio amateur]] and worked as an assistant to [[Lee De Forest|Lee de Forest]]. He studied electrical engineering at Sheffield Scientific School at Yale University, where he earned honors in physics and mathematics, and in 1909 became a telegraph engineer for [[Reginald A. Fessenden|Reginald Fessenden’s]] National Electric Signaling Company. He was the Chief of the Operating, Erection and Inspection Department of the company during the extremely important long-range radio tests using the United States Navy’s then new Arlington wireless station and the cruiser USS Salem, which were carried out during the winter of 1912-1913. The Salem sailed from the Delaware River east across the Atlantic Ocean to Gibraltar. The transmitting station at Arlington possessed high-power spark-gap as well as electric-arc dischargers, and it sent test messages to the ship alternately using one type then the other. By the time the Salem reached a distance of 1200 miles (1920 km) signals from the arc were beginning to be stronger than the ones from the spark. Moreover, the messages sent via arc could be heard at Gibraltar, 6400 km away, during the hours of daylight. The experiments confirmed the Austin-Cohen formula for radio wave propagation and showed the feasibility of continuous wave transmission over very long distances.
  
Hogan's main interest, however, had by then turned to facsimile transmission over radio waves, leading to his development of a machine capable of producing a 4-column newspaper, complete with illustrations, at the rate of 500 words per minute.

In 2009, the renowned classical music radio station, WQXR — which was the last commercial classical radio station in the New York City area — sold its frequency, and became part of the public radio network at a new frequency and at one tenth its former signal strength. Among WQXR’s founders was former IRE President John Vincent Lawless Hogan. John V. L. Hogan was not only a prolific inventor who presided over some important developments in radio and facsimile, he was also a crucial early leader who shaped the IRE — and thus IEEE’s — institutional history.

He was born in Philadelphia, Pennsylvania, U.S.A. on 14 February 1890 and was raised in New York, where he attended the Horace Mann School. As a teenager, he was a radio amateur and worked as an assistant to Lee de Forest.

Moreover, the messages sent via arc could be heard at Gibraltar, 6400 km away, during the hours of daylight.
