'Dr Robert Hutchings Goddard (1882-1945) and a liquid oxygen-gasoline rocket in the frame from which it was fired on 16 March 1926, at Auburn, Massachusetts. From 1930 to 1941, Dr Goddard made substantial progress in the development of progressively larger rockets, which attained altitudes of 2400 meters, and refined his equipment for guidance and control, his techniques of welding, and his insulation, pumps and other associated equipment. In many respects, Dr Goddard laid the essential foundations of practical rocket technology. He is considered one of the fathers of rocketry along with Konstantin Tsiolovsky (1857-1935) and Hermann Oberth (1894-1989).'
