John L. Lewis
(1839 -1911)

John Lester Lewis was born in South Pittsburgh, Pennsylvania (though some researchers have said Wales), on March 17, 1839, the son of Rachel Williams and John Lewis (both born in Wales). He married (1) Sarah Greer (1842-1866) and (2) Anna "Annie" Charlotte Glosser (1849-1918), and had nine children.

Lewis served in the Civil War for a year and a half (1864-1865), in the Fourth Pennsylvania Cavalry, and in Company C of the Fifth Heavy Artillery. Around 1870, he and others organized the Lewis & Rossiter Foundry Company in Pittsburgh; after the retirement of Rossiter, it became the Lewis Foundry & Machine Company, specializing in castings and rolling mill equipment. Lewis remained the principal owner and president until his retirement.

Between 1902 and 1910, Lewis donated more than 2,600 gem crystals and cut gemstones, pearls, and pearl-bearing shells to the Carnegie Museum of Natural History. The acquisition of these gemstones was Lewis' "labor of love" for 30 years. Among them were cut stones from California such as chrysoprase, rough and cut chalcedony from Catalina Island, and tourmaline crystals from San Diego County.

He died in Erie, Pennsylvania on November 16, 1911.
