Louis Blanchard Wilson (December 22, 1866 – October 5, 1943)[1] was an American pathologist and the chief of pathology at Mayo Clinic from 1905 to 1937.
Wilson is most famous for initiating the routine use of the frozen section procedure for rapid intraoperative diagnosis.
On January 1, 1905, Wilson began working at Mayo Clinic as the chief of pathology and he initiated a new scientific way of doing things at St. Marys Hospital.
Wilson began using a frozen section technique he created in 1905 and published a paper on his method in JAMA at the end of that year.
Dr. Wilson's home where he lived with his second wife Maud Mellish, Walnut Hill (architect Harold Crawford), is extant on the grounds of the Assisi Heights convent in Rochester Minnesota and owned by the Mayo Clinic.
