Ignaz Heymann (1765-1815) was an Austrian postmaster, publisher, and cartographer active in Italy during late 18th and early 19th century. Heymann was born in Karansebes (modern day Romania). At age 7 he moved with his parents to Milan where, as a young man, he attended the Jesuit College of Brera. In 1874 he traveled throughout Italy, visiting Florence, Rome, Naples, and Venice, finally landing in Gorizia, where he took a job with the local tax regulatory commission. Afterwards he relocated to Trieste where he found work with the Postal Service. The Napoleonic occupation of Trieste in 1809 forced him to move again, this time to Vienna, where he again took work with the postal service. He retired from the postal service in 1811, after 25 years of service. For his distinguished civil service to the Hapsburg Empire he was awarded the Große Goldene Civil-Verdienstmedaille (Great Golden Civil Merit Medal). He published a number of large format maps, most associated with the postal service. His earliest cartographic studies appeared in 1797. Numerous maps followed, most depicting various parts of the Hapsburg Empire and Italy. Heymann died in 1815.
