Biographical History

Thomas Coulter (1793-1843) was born on September 28, 1793, in Dundalk, Ireland. He studied medicine at Trinity College in Dublin, and later worked at the Jardin des Plantes in Paris. Coulter traveled to Mexico in 1824 to take a post as physician to the Real del Monte Company, a silver mining company. He collected plants in Mexico and California from 1824 to 1834. While in California, he was credited with discovering the Colorado Desert. Once returning to Ireland, his personal specimen collection helped found the herbarium at Trinity College, where he was named the first curator in 1840. Coulter died at Trinity College on November 28, 1843.
