Thanks for giving us her full name pennylrichardsca, we'll update the catalog record. Is that Sir Arthur Conan Doyle on the right?

It certainly does look like the famous creator of the immortal sleuth, Sherlock Holmes. Here is Conan Doyle as a young man (in another Bain Agency portrait):

Katharine Dexter McCormick (August 27, 1875 – December 28, 1967) was a U.S. biologist, suffragist, philanthropist and, after her husband's death, heir to a substantial part of the McCormick family fortune. She is remembered for funding most of the research necessary to develop the first birth control pill. Notably, her husband does not have a Wikipedia entry (yet)...

She was the granddaughter of Judge Samuel William Dexter, the founder of Dexter Village, MI (about ten miles west of my hometown of Ann Arbor), and the daughter of Wirt Dexter, prominent Chicago attorney and financier. (The Louis Sullivan-designed Wirt Dexter Building, a Chicago landmark, burned to ashes a few years ago.) Katharine's husband was the fabulously wealthy Stanley McCormick of Chicago, a member of the family that invented the McCormick Reaper and founded the International Harvester Company. Unfortunately, Stanley McCormick went mad.

She's also familiar as one of the main characters in TC Boyle's Riven Rock, a novel based on the story of Stanley McCormick's madness and retreat to an estate near Santa Barbara.

episodesandaccidents, Wystan and pennylrichardsca--thank you for identifying Katherine Dexter McCormick. We will add some of these details to the record when we update.

Could this perhaps have been taken at Longchamp?
