Harold E. Froehlich - Designer of Alvin submarine
Thursday, May 24th, 2007
The three-man, deep-sea diving submarine, Alvin, took us all on adventures that have fascinated people around the world since its maiden voyage in 1964. Harold (Bud) Froehlich was the vessel’s chief designer.
Harold E. Froehlich was already thinking deep after helping to build a mechanical arm for the Navy-owned bathyscaph Trieste, when in 1962 he became project manager at General Mills for the Navy/ Woods Hole Oceanographic Institute project to build the small, deep-diving submarine.
Alvin’s assignments have taken it as deep as 15,000 feet below the surface of the ocean, where it has helped find a hydrogen bomb, explored the wreckage of the RMS Titanic, discovered unimagined deep-sea animals and plants, and vicariously peered in the depths for armchair explorers everywhere.
Over Alvin’s 45 years every single piece of it has been replaced. A new generation submarine is due to replace it in the next year or so.
Always driven to “figure things out,” Harold E. Froehlich worked on diverse projects throughout his career such as high-altitude balloons and surgical equipment. He retired in Minneapolis, MN after working at 3M. He died there of cancer May 19, 2007 at age 84.
