Felix von Winiwarter (February 28, 1852 – July 10, 1931) was an Austrian physician who was a native of Vienna.
Soon afterwards, he became a surgical apprentice to Theodor Billroth (1829–1894), and from 1878 to 1881 worked as a secondary physician under Leopold Ritter von Dittel (1815–1898).
He was a younger brother to Alexander von Winiwarter (1848–1917), who also spent part of his career working with Theodor Billroth.
Winiwarter's discovery wasn't the first modern description of the condition, as three years earlier, bacteriologist Carl Friedländer (1847–1887) referred to it as "arteritis obliterans".
In 1908, American surgeon Leo Buerger (1879–1943) further described the disease, and in 1924 published a monograph based on analyses taken from 500 patients.
