John E. Weyss
Major John E. Weyss (1820 in Vienna – 24 June 1903 in Washington), was an Austro-American artist, cartographer and engineer who served with the US Corps of Topographical Engineers for some 40 years.
Weyss was a member of William H. Emory's team that surveyed the US-Mexico border. He contributed profusely to the "Report on the United States and Mexican boundary survey" of which the first volume was published in 1857.
Weyss was in charge of detailed mapping at Petersburg when it was besieged during the American Civil War. Weyss in turn reported to Major Nathaniel Michler, head of the topographic department for the Army of the Potomac. Michler graduated from West Point Military Academy in 1848.
