      American engineer

born July 13, 1922, Minneapolis, Minn.

died May 19, 2007, Maplewood, Minn.
led the team at General Mills that designed Alvin (named for oceanographer Allyn C. Vine), a three-person submersible equipped with a mechanical arm and built to withstand pressures in the deep seas. The minisub, which was launched in 1964, was commissioned by the U.S. Navy but operated out of Woods Hole (Mass.) Oceanographic Institution. Alvin was used to map the Mid-Atlantic Ridge (the underwater mountain chain in the centre of the Atlantic Ocean), to recover an errant hydrogen bomb in 1966, and to lead co-developer Robert Ballard to the wreckage of the Titanic. Froehlich later joined the 3M Corp., where he worked on devising navigation buoys and medical products. He retired in 1989.
