Walter began tinkering as a young boy and from an early age displayed an uncanny knack for taking things apart in order to see how they worked. Even so, there was a time or two as a teenager when his experimentation proved to be unpredictable and he nearly blew himself up. His parents were often not amused. After attending
Hillyer College, Walter worked for companies such as Hartford Machine Screw and DeBell & Richardson Labs. Later, he began to offer his services as a freelance design engineer, a change that enabled him to spend more time with his growing family. “My father believed that nothing was impossible,” said Carol. “Sometimes when he was brainstorming on his own he’d do something that reflected his deep faith – like the day he was testing the jet engine he invented. He mounted it on an armature in our backyard and it went around in circles so fast that you couldn’t even see it. He was brilliant and he knew nothing would go wrong, but the whole neighborhood thought a jet fighter had landed in the backyard.” Once the Air Force undertook a detailed study of the Lovell Ramjet design, they appropriated it for national defense purposes. But Walter had no hard feelings. “My dad loved this country,” said Carol.
