Heinrich (Henry) Freidrich Wilhelm August Barkschat (20 May 1884 - 9 October 1971), was a Prussian-born inventor and mining engineer. He arrived at Ellis Island, New York on the SS Zeeland, from Antwerp, Belgium in 1907. In 1910 he worked as a consultant mining engineer in residence in Arizona, where he began to develop a group of mining claims near Walker.[1] Mr. Barkschat purchased the 'Cowboy' mine near Prescott in the hillside district, near the productive Bagdad Mine and then took leadership in the Yavapal Metals Mining and Reducing Company (YMMRC), a high grade gold-copper ore mine near Humboldt, Arizona Humboldt, Arizona.[2] For his contributions to the copper mining industry in the State of Arizona, Barkschat was featured in the Journal: Being the Portraits and Biographies of Progressive Men of the West.[3]


Mr.Barkschat invented a formulation process for engineering durable concrete cylinders that could be made into lamppost standards and conduits for telephone lines, sewer and high-pressure pipes. [4] These innovative concrete lampposts changed the course of municipal electric lighting, with over 60 cities from Los Angeles to Chicago mass installing these standards due to their weathering capabilities. [5]. Mr. Barkschat wrote of his novel concrete lamp post : "In too many cities do we find sombre, ill-proportioned and over decorated iron lighting standards. In addition to falling short of modern standard design, such poles require constant maintenance for painting, if they are to be kept in passable condition." [6]

These distinctive lampposts continue to line many streets in the historic districts of California: Los Angeles (Griffith Park), South Redlands, San Pedro, and Lake Elsinore's Clevelin Hills. [7]

The Barkschat inventions were secured with patents for: centrifugal molding [Standards]:the lamp post construction: a centrifugal cement mold apparatus[8]; a hollow cement mold ( US1474881A August 1919); a municipal lantern construct; [9] and a centrifuge and mold holder (March 29, 1926 Patent US 1663896A).[10] [11]

In 1923, Mr. Barkschat orchestrated the merger of the National Concrete Production and the American Cement Products Companies, which laid the foundation for the Marbelite TM Corporation."An amalgamation ... was completed yesterday with the announcement that the Marbelite Corporation of America had taken over the plants ...and... incorporated for $1,000,000 and will be headed by Henry Barkschat as president".[12].

In 1925, Mr. Barkschat in partnership with Henry Cleveland Schultz and Abe Corlinsky founded the Clevelin Construction Corporation, funded by Marbelite capital. Over 1100 Marbelite concrete lamppost electroliers were installed along subdivision's roadways in and around the Country Club Heights District of Lake Elsinore, California. [13]. Mr. Barkschat has a street named after him, Barkschat Drive, in the Clevelin Hills area of Lake Elsinore.[14]
