Sol Steinmetz

Sol Steinmetz (July 29, 1930 – October 13, 2010) was a Hungarian American linguistics and lexicography expert who wrote extensively about etymologies, definitions and uncovered earliest recorded usages of words in English and Yiddish. A widely sought source on all things lexical, he earned recognition from William Safire in his ''On Language'' column in ''The New York Times Magazine'' in 2006 as a "lexical supermaven".
