Biography
Born in New Haven, Connecticut to a medical family, MacCready was an inventor from an early age and won a national contest building a model flying machine at the age of 15.
MacCready graduated from Hopkins School in 1943, received his BS in physics from Yale University in 1947, a MS in physics from Caltech in 1948, and a PhD in aeronautics from Caltech in 1952. He trained as a US Navy pilot at the end of World War II. In 1951 MacCready founded his first company, Meteorology Research Inc, to do atmospheric research. Some of MacCready's work as a graduate student involved cloud seeding.
He started gliding after World War II and was a three-time winner (1948, 1949, 1953) of the Richard C. du Pont Memorial Trophy, awarded annually to the U.S. National Open Class Soaring Champion. In 1956 he became the first American pilot to become the World Soaring Champion. He devised the MacCready Theory on the correct speed to fly a glider depending on conditions and based on the glider's rate of sink at different air-speeds. Glider pilots still use the "MacCready speed ring".
With Dr. Peter B.S. Lissaman he created a human-powered aircraft, the Gossamer Condor, and thereby won the Kremer prize in 1977. The award-winning plane was built out of aluminium tubing, plastic foam, piano wire, bicycle parts, and mylar foil for covering. In 1979, he built its successor, the Gossamer Albatross, which won the second Kremer prize for successfully flying from England to France.
He later created solar powered aircraft such as the Gossamer Penguin and the Solar Challenger. He was involved in the development of NASA's solar-powered flying wings such as the Helios, which surpassed the SR-71's altitude records and could theoretically fly on Mars (where the atmosphere is thin and has little oxygen). MacCready also collaborated with General Motors on the design of the Sunraycer, a solar powered car, and then on the EV-1 electric car.
In 1985 he was commissioned to build a halfscale working replica of the pterosaur Quetzalcoatlus for the Smithsonian Institution, following a workshop in 1984 which concluded that such a replica was feasible. The completed remote-controlled flying reptile, with a wingspan of 18 feet, was filmed over Death Valley, California in 1986 for the Smithsonian's IMAX film On the Wing. It flew successfully several times before being severely damaged in a crash at an airshow at Andrews AFB in Maryland. The launch of the dinosaur model came off well but the radio transmitter link failed, perhaps due to the interference from some of the many base communications devices. The model nosed over and crashed at the runway side, breaking at the neck from the force of impact.
MacCready helped to sponsor the Nissan Dempsey/MacCready Prize which has helped to motivate developments in racing-bicycle technology, applying aerodynamics and new materials to allow for faster human-powered vehicles.
He was the founder (in 1971) and Chairman of AeroVironment Inc., a public company (AVAV) that develops unmanned surveillance aircraft and advance power systems. AV recently flew a prototype of the first airplane to be powered by hydrogen fuel cells, the Global Observer.
MacCready died on August 28, 2007 from metastatic melanoma.

Famous quotes containing the word biography:
“As we approached the log house,... the projecting ends of the logs lapping over each other irregularly several feet at the corners gave it a very rich and picturesque look, far removed from the meanness of weather-boards. It was a very spacious, low building, about eighty feet long, with many large apartments ... a style of architecture not described by Vitruvius, I suspect, though possibly hinted at in the biography of Orpheus.”
—Henry David Thoreau (18171862)
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, memoirs to serve for a history, which is but materials to serve for a mythology.”
—Henry David Thoreau (18171862)
“Had Dr. Johnson written his own life, in conformity with the opinion which he has given, that every mans life may be best written by himself; had he employed in the preservation of his own history, that clearness of narration and elegance of language in which he has embalmed so many eminent persons, the world would probably have had the most perfect example of biography that was ever exhibited.”
—James Boswell (174095)
