“We actually have a picture of the moment we met,” Ms. Lynch said, referring to the May 2009 San Francisco fund-raiser at which she was a presenter and Dr. Embry, who was among those being honored, instigated their introduction.  “I said, ‘I want my picture taken with her,’ ” Dr. Embry recalled. “I thought she was cute.”   Both say that the attraction between them was immediate and that their differing professions played no part in it.  “It’s not like she’s marrying out of her species or anything,” Ms. Lynch said.  Dr. Embry noted: “I knew of her work, but not extensively. I was basically ignorant of it.”
