Sept. 18, 1920

As Molla Bjurstedt of Norway, she won four consecutive United States National championships starting in 1915. Now, on this day, as Molla Bjurstedt Mallory after marrying stockbroker Franklin Mallory, she is gunning for No. 5 as a U.S. citizen. She has little difficulty, needing just 30 minutes to dethrone defending champion Marion Zinderstein 6-3, 6-1 in Philadelphia.

Mallory will go on to win three more U.S. titles after the women's tournament shifts to Forest Hills the next year, and her eight championships are still the record today.
