Evo of Tech: Harold Froehlich invents Alvin deep sea submersible while working at General Mills labs

Interestingly enough, the world of deep sea exploration actually owes a great deal of gratitude to a major American cereal company for providing a major advance in submersible vehicle technology. Sunday, September 24th, marked the 54th anniversary of the issue of patent covering an underseas vehicle technology issued to Harold Froehlich, then an engineer at General Mills. This May, Froehlich was included among the inductees of the National Inventors Hall of Fame’s 2017 class for his work in developing the deep sea human occupied vehicle Alvin.
