Biography

Dryden was born in Pocomoke City, Maryland, the son of Samuel Isaac and Nova Hill Culver Dryden, and was named after a popular local Methodist clergyman. During the financial panic of 1907, his father lost his job and the family moved to Baltimore, Maryland.

As a student, Dryden excelled in mathematics. He graduated from Baltimore City College, a high school, at the age of 14, and was the youngest student ever to graduate from that school. He was awarded the Peabody Prize for excellence in mathematics. With a scholarship, he was admitted to Johns Hopkins University and graduated with honors after only three years. He earned a M.S. in physics in 1916. His thesis was titled, "Airplanes: An Introduction to the Physical Principles Embodied in their Use."

In 1918, Dryden joined the National Bureau of Standards, becoming an inspector of gauges. With the help and influence of Dr. Joseph S. Ames, he obtained a transfer to the bureau's Wind Tunnel division, and began taking graduate courses in fluid dynamics to complete his Ph.D. In 1919 at the age of 20, he was awarded his degree in physics and mathematics from Johns Hopkins University, the youngest person ever to have received a doctorate from that institution. His thesis was on the "Air Forces on Circular Cylinders".

In 1920 Dryden was appointed the director of the Aerodynamics Division of the National Bureau of Standards, a newly created section. Collaborating with Dr. Lyman J. Briggs, he performed studies of airfoils near the speed of sound. He also performed pioneering aerodynamics research on the problems of airflow, turbulence, and especially the boundary layer phenomenon. His work contributed to the design of the wings for the P-51 Mustang, as well as other aircraft designed during World War II.

By 1934, Dryden was appointed the bureau's Chief of the Mechanics and Sound Division, and in 1939 he became a member of the National Advisory Committee for Aeronautics (NACA).

With the start of World War II, Dryden served in an advisory capacity to the Air Force. He led the development of the "Bat", a radar-homing guided bomb program that was successfully employed in combat in April, 1945 to sink a Japanese destroyer.

After the war, Dryden became the Director of Aeronautical Research for the National Advisory Committee for Aeronautics (NACA) in 1946. While at the NACA he supervised the development of the North American X-15, a rocket plane used for research and testing. He also established programs for V/STOL aircraft, and studied the problem of atmospheric reentry.

He held the position of Director of NACA, NASA's predecessor, from 1947 until October 1958. In addition he served on numerous government advisory committees, including the Scientific Advisory Committee to the President. From 1941 until 1956 he was editor of the Journal of the Institute of the Aeronautical Sciences. After NACA became NASA, he became the Deputy Director of that organization, serving until his death.

He died from cancer on December 2, 1965.

Michael Gorn, chief historian at NASA Dryden Flight Research Center, described Dryden as a quiet, reserved man who was self-effacing and diligent. He was patient, a good teacher, and effective when collaborating with others. He was also a devout Methodist, who, as a result, had a dislike of self-promotion. He served as a lay minister for his entire adult life. He was married to Mary Libbie Travers, and the couple had four children.

Tom Wolfe, writing in 2009 at the 40th anniversary of the launch of Apollo 11, credited Dryden with having been the individual who spoke up, with President John F. Kennedy in April, 1961, and suggested that manned flight to the moon was the way to "catch up" with the Soviets in the space race. Wolfe describes President Kennedy as having been in "a terrible funk" at the time of the meeting with James E. Webb, the NASA administrator, and Dryden, his deputy, as the president wrestled with the string of Soviet "firsts" in space flight which had started with Sputnik 1 in 1957 and, that month in 1961, had extended to include human earth-orbital flight. Within a month of the meeting with Webb and Dryden, President Kennedy announced the Apollo Project-scale goal of putting a man on the moon within 10 years, the goal that Apollo 11 was ultimately to meet. In setting the goal, the president did not credit Dryden's input, according to Wolfe.

Dryden is also a founding member of the National Academy of Engineering.

Dryden was portrayed by George Bartenieff in the 1998 TV miniseries From the Earth to the Moon.
