Leopold Ritter von Dittel (May 29, 1815 – July 28, 1898) was an Austrian urologist born in Fulnek, a community now located in the Czech Republic. Dittel received his medical doctorate in 1840 from the University of Vienna, and as a young man worked as a physician in Trentschin-Teplitz. From 1853 to 1857, he was an assistant to Johann von Dumreicher (1815-1880) and a surgical assistant at the university hospital in Vienna. Later, he became surgeon-in-chief of the Allgemeines Krankenhaus, and in 1865 attained the title of associate professor.
