Charles Theodore Mohr
baptized Karl Theodor Mohr]

Charles Mohr was one of Alabama’s first botanists. He was born in Germany and educated in Stuttgart. He collected in Suriname (1845-1846) and emigrated to the United States in 1848. After traveling to California in the gold rush, living briefly Mexico, Indiana, and Kentucky, he settled in Mobile, Alabama in 1857 and operated Chas. Mohr & Son Pharmacists and Chemists in Mobile, Alabama. Mohr was granted an honorary Ph.D. in 1893 by the University of Alabama in recognition of his contributions to the knowledge of the State’s flora and geology. He is best known as the author of Plant Life in Alabama, published in 1901.

Most of Mohr’s botanical specimens were given to the University of Alabama Herbarium (UNA, ca. 15,000 specimens; and to the United States National Herbarium (US, ca. 18,000 specimens; The University of North Carolina Herbarium has several dozen collected by Mohr (mostly from Alabama ca. 1880-1890); without doubt additional specimens will be found as our collection continues to be cataloged and databased.

On December 18, 2004, Ms. Elizabeth Burch Heston (UNC Class of 1954, and great-great-granddaughter of C. T. Mohr) honored her ancestor by founding and endowing the Charles T. Mohr Herbarium Internship Fund to be used to support student interns working with mentors at the University of North Carolina Herbarium.
