Whic First Lady Rode in NYC's First Elevator?

And the answer is ...

b) Mary Todd Lincoln

Mrs. Lincoln was a regular shopper at Eder V. Haughwout's, a store in the building with New York's very first elevator. The emporium, which took up most of the building's five floors, was a favorite among NYC elite for glass, china, and other housewares. Although the store is no more, the building has become a New York landmark, with the original elevator still in place!
