## Career

Lewis was born in Philadelphia on November 16, 1853, and was educated at the University of Pennsylvania.[1] He received his Masters of Arts Degree in 1876 and became attached to the Geological Survey of Pennsylvania in 1879. He served for three years as a volunteer member, and during this term he became greatly interested in the study of glacial phenomena. In 1880 he was chosen professor of mineralogy in the Philadelphia Academy of Natural Sciences, and in 1883 he was appointed to the chair of geology in Haverford College, Pennsylvania. He was elected as a member to the American Philosophical Society in 1881.[2]

During the winters of 1885 to 1887 he studied petrology under HF Rosenbusch at Heidelberg, and during the summers he investigated the glacial geology of northern Europe and the British Isles. His observations in North America, where he had studied under Professor G.F. Wright, Professor T.C. Chamberlin and Warren Upham, had demonstrated the former extension of land-ice, and the existence of great terminal moraines.

In 1884 his Report on the Terminal Moraine in Pennsylvania and Western New York was published: a work containing much information on the limits of the North American ice-sheet. In Britain he sought to trace in like manner the southern extent of the terminal moraines formed by British ice-sheets, but before his conclusions were matured, he died from typhoid fever at Manchester, England on July 21, 1888.[1][3] He was buried at the churchyard of Christ Church, Walmsley.[4]

The results of his observations were published in 1894, entitled Papers and Notes on the Glacial Geology of Great Britain and Ireland, edited by Dr HW Crosskey.

## Psychical research

Lewis took interest in investigating paranormal claims. In 1886, he attended séances of the medium William Eglinton and detected him in fraud.[5][6] The exposure was published in the Proceedings of the Society for Psychical Research in 1887.
