FREDERICK A.KAMPFE DIES IN WASHINGTON

Former Brooklynite, With His Brothers, Invented First Safety Razor.

Frederick A. Kampfe, formerly a well-known resident of Brooklyn, died on Wednesday at his home, 2309 Calvert street, N. W., Washington, D. C., where he had resided for the past five years. Mr. Kampfe had suffered several strokes of apoplexy, and his death is believed to have been from paralysis. The funeral services will be held this evening at his late home in Washington and the remains will be brought to Brooklyn for interment in Greenwood Cemetery tomorrow afternoon. Mr. Kampfe lived for many years on Logan street, in the Twenty-sixth Ward, where he had large grounds surrounding his residence. The grounds were a show place, laid out as a beautiful garden.
Mr. Kampfe was one of three brothers, Richard, Otto and Frederick, who composed the firm of Kampfe Bros., for many years in business as general machinists on Chambers street, Manhattan, and widely known as the inventors and patentees of the first safety razor, in 1880. When the three brothers invented a razor that would shave without cutting the flesh they were in humble circumstances. The invention made them rich, and all three owned large parcels of land here, on Long Island and in New Jersey. Richard Kampfe, the oldest of the brothers, died in 1906. Otto is still living on Long Island. Otto had a large place on Liberty avenue for several years, where he kept a sort of menagerie with all sorts of wild animals, that was the show place of that section of East New York.
Frederick A. Kampfe was born in Dresden, Saxony, and came to New York City as a boy with his brothers. He had a fine country residence at Bloomingdale. N. J., not far from his brother’s large summer place at Butler, and he spent his summers there and his winters in Washington. He was a Freemason. He is survived by his wife, Barbara; a daughter, Flora; two brothers, Otto and Rudolph, and several nephews and nieces; also three sisters, who live in Germany.
