Rudolf Robert Maier

Rudolf Robert Maier (April 9, 1824 – November 7, 1888) was a German pathologist who was a native of Freiburg im Breisgau.

He studied medicine at the University of Freiburg, where one of his instructors was orthopedist Louis Stromeyer (1804–1876). He furthered his medical training in Vienna with Carl Rokitansky (1804–1878), Joseph Hyrtl (1810–1894) and Josef Skoda (1805–1881), and in Würzburg under Rudolf Virchow (1821–1902). Afterwards, he returned to Freiburg, where in 1859 he became an associate professor. He later attained a full professorship, and in 1864 founded the first institute of pathological anatomy at Freiburg.

With Adolf Kussmaul (1822–1902), Maier provided the first comprehensive description of periarteritis nodosa, a condition sometimes referred to as "Kussmaul-Maier disease". The two doctors described their findings in the inaugural edition of the journal Deutsches Archiv für klinische Medicin, a publication co-founded by Friedrich Albert von Zenker (1825–1898) and Hugo Wilhelm von Ziemssen (1829–1902).

He died in 1888 following a massive goiter disease with bronchoconstriction.
