Selmar Siebert (September 4, 1808 - September 1885) was a German printer and engraver active in Germany and the United States. Siebert was born in Lehnin, Prussia, in 1808. He engraved maps for the Justus Perthes firm and for Heinrich Berghaus (1797 - 1884). From 1835, he worked with the Schleswig-Holstein land survey. He emigrated to the United States in 1842, initially taking work as an engraver for the then fledgling U.S. Coast Survey. By 1747, he was the senior engrave of the D.C. office. Around 1950, he set up an engraving, lithography, and printing firm in Washington D.C. Around the same time, in 1851, he married Emma Gildemiester at the Concordia Lutheran Evangelical Church. Siebert remained active in Washington until 1861, when the outbreak of the American Civil War (1861 - 1865) force him and his family back to Germany. He died at sea in 1885. His son, Edward Selmar Siebert (1856 - 1944), became a well-known painter.
