Stephan Schulzer von Müggenburg (December 19, 1802 – February 5, 1892) was a Hungarian-Croatian army officer and mycologist.

[1] Schulzer von Müggenburg was born into abject poverty in a dilapidated castle at the periphery of the Austro-Hungarian Empire.

He was brought up by, and received a Spartan home-education from, his well educated but very strict father, a retired army officer of Saxonian descent, who died when Schulzer was fifteen.

He however volunteered to establish and manage a military hospital where he fell victim to a disease which left him deaf and vision impaired.

Much of his work remains unpublished, but some was edited and published by his colleagues and at times scientific rivals Károly Kalchbrenner and Friedrich von Hazslin.
