Harry Julian Allen

Index Harry Julian Allen

Harry Julian Allen (1 April 1910 – 29 January 1977), also known as Harvey Allen, was an aeronautical engineer and a Director of the NASA Ames Research Center, most noted for his "Blunt Body Theory" of atmospheric entry which permitted successful recovery of orbiting spacecraft. [1]
