    Biographical / Historical

    Edward Hoit Nutter was born May 24, 1876, in Healdsburg, California. He attended Stanford University and received a degree in mining and geology. Nutter worked for several mining companies around the United States before going to London in 1910 to work for Minerals Separation, Ltd., where he helped develop and introduce their flotation process to the United States and Canada. Through his work for the firm and its American subsidiary, the Minerals Separation American Syndicate Ltd., Nutter was involved in the evolution of the technology as well as efforts to control it by taking out multiple patents. Nutter married Gertrude Monier Allen in 1905, and the couple had three children: Edward Allen, Katherine Louise, and Sheldon Hoit. He remained connected to Stanford University throughout his life and after his retirement began to study Emanuel Swedenborg, the 18th century Swedish metallurgist and philosopher who founded a religion. Edward Hoit Nutter died March 1, 1960, in Los Gatos, California.
