Martin Hans Boyč, December 6, 1812, Copenhagen, Denmark - March 6, 1907, Coopersburg, Pennsylvania. Boyč emigrated to the US from Denmark in 1836. He worked as a geologist and chemist on a geological survey of the anthracite coal regions in Pennsylvania and as a chemist at the State Laboratories in Philadelphia (208 Chestnut St) before receiving his MD degree from the University of Pennsylvania in 1844. In 1847 he invented a process of refining cottonseed oil which he later manufactured on a large scale. Other researches included an analysis of concretion from a horse's stomach and analysis of Chinese artifically colored tea. In 1851 he was Chair of Chemistry in Central High, Philadelphia, but resigned in 1859 because of poor health. [Smith, Edgar F., --Martin Hans Boyč, Chemist.-- Philadelphia, 1924]
