Logan, Sir William Edmond (1798-1875), a Canadian geologist, gained fame for his pioneer work researching coal, glacial action, early fossil evidence of life, and ancient rocks. Logan was born in Montreal and educated in Scotland. During much of the 1830’s, he studied coal deposits in Wales. He then returned to Canada to continue his research. In 1842, Logan became the first director of the Geological Survey of Canada. His most important book was A Report on the Geology of Canada (1863).
