Did you Mary Clark Thompson, Sonnenberg's original owner, is the same Mary Clark Thompson for whom the National Academy of Science named their award of the same name?
She donated the funds for the award in 1919 and a gold medal used to be awarded annually but is now presented every three years, along with a $15,000 prize (courtesy of Mary Clark Thompson's endowment) to honor important services to geology and paleontology. Here is a link to an American Association for the Advancement of Science publication from 1919, which briefly mentions the award.
Mrs. Thompson was a great philanthropist and gave to innumerable causes in Canandaigua and beyond, many of which were related to the fields of healthcare and science.
