    Thomas Henry Huxley

    Huxley is an example of having a good attitude about publicly acknowledging errors and learning from them. He earned the nickname “Darwin’s bulldog” for his very vocal support of Darwin’s work, and he wanted to promote science and education, particularly to people that didn’t normally have access to those things.  Research: Bernoulli, D., Jenkyns, H.C. “Thomas Henry Huxley, a stone tablet, coccoliths, and deep-sea sediments in the high Alps.” Int J Earth Sci (Geol Rundsch) 112, 1661–1669 (2023). https://doi.org/10.1007/s00531-023-02330-5 Bowen, Keith. “Thomas Henry Huxley.” Ebsco. 2024. https://www.ebsco.com/research-starters/history/thomas-henry-huxley Burkhardt, Richard W..
