Frederick Pearson Treadwell
Frederick Pearson Treadwell , also Frédéric, (born February 5, 1857 in Portsmouth (New Hampshire) , † June 24, 1918 in Zurich ) was an American-Swiss chemist.
Life
Treadwell grew up as the son of an American merchant ship captain who sent him to Europe to study. After language studies in Gotha , Treadwell studied chemistry in Heidelberg from 1875 to 1878, where he did his doctorate with Robert Bunsen and then worked as his assistant.
In 1881 Treadwell moved to Zurich and worked under Viktor Meyer . He was appointed private lecturer in 1882 and honorary professor in 1884, was particularly active in the field of analytical chemistry and was given a full professorship in analytical chemistry at the ETH Zurich in 1893 . Treadwell wrote a widely used textbook on analytical chemistry . He obtained Swiss citizenship in Zurich in 1905.
Initially he dealt with organic chemistry (for example synthesis of nitrosoketones) and from the beginning of the 1880s with analysis . He developed a detection method for chromium ions, dealt with gas analysis and improved the method for determining sulfur. In 1900 he found a method for the simultaneous detection of nickel and cobalt and their separation.
His son William Dupré Treadwell was also a well-known analyst and his successor from ETH Zurich.
