Eduard Grégr (also Gröger), along with his brother Julius, was one of the leaders of the Young Czech Party.
Eduard began his career as a medical doctor and writer of popular science articles during the 1850s.
After graduating from medical school in 1854, he also served as a research assistant to Purkyne who wrote about anthropology and biology.
He stopped practicing medicine and conducting scientific experiments in 1862 so that he could focus on a full-time political career.
Unlike his brother Julius, Eduard's temperament was characterized as very calm, warm and generous.
