Fisher founded Gap with her late husband, Don, in 1969. She and her three sons still own stakes in the $16.6 billion (revenue) retail group, whose shares dropped roughly one fourth in the last year. It is planning to spin off Old Navy into its own publicly traded entity, but will still hold the Banana Republic and Athleta brands.
