Ernest W. Chapman

Ernest William Chapman of Pasadena, California was born in Dunstable, Massachusetts on October 9, 1894, the son of Elizabeth Blanche Blood (daughter of Washington Blood) and Frank Chapman, a farmer. Ernest left home some time after 1910, married and had a child (their names are unknown but the marriage didn't last); in 1917 he was working as a rubber worker for the Portage Rubber Co. in Barberton, Ohio. By 1920 he was single again, working as a laborer in a sawmill in Stanwood, Snohomish County, Washington. Shortly thereafter he moved to California, where he married a second time (Irene W.) in 1922. As of 1930 they were living in Alhambra, Los Angeles Co., California where he was working as a mill-man in a lumber yard. He had moved to Pasadena by 1937, and lived there the rest of his life.

Ernest Chapman began collecting minerals and studying mineralogy in 1924. He was a prominent member of the Mineralogical Society of Southern California since its founding. He built a beautiful, well-known, and very well-selected collection of minerals representing most of the important mineral localities in America, and was always happy to display it at local gatherings and meetings. Well-crystallized specimens predominated, but massive specimens were also included as necessary. Chapman was a regular field collector, and thus an important part of his collection consisted of minerals personally collected at important localities in California and neighboring states. He was generous with his time, always willing to be a speaker at the meetings of many of the various mineralogical organizations in Southern California. He believed that mineral collectors and amateur mineralogists could and should contribute to the advancement of mineralogical science.

He was not a writer, but in 1933 he published a short illustrated article in Rocks & Minerals, on "The Devil's Postpile" on the San Juaquin River in California. Ernest Chapman died suddenly on September 17, 1947 at his home in South Pasadena, California.
