Alexander Zakreski (1799-1866), born Aleksander Zakrzewski, was a brilliant Polish military engineer and revolutionary who had to flee his native land owing to his opposition to Russian rule. He then settled in France where he lithographed a map of Paris in 1839. He was subsequently caught up in the Revolution of 1848 and had to leave the county, finally arriving in San Francisco in 1850. Zakreski soon found work as a mapmaker and lithographer, working with various governmental agencies, as well as commercial publishers. In 1852, he worked closely with the County Surveyor's Office.
Among his most important works were his early maps of San Francisco.
