Fisher, who serves as the company's chairman, replaced 15-year Gap veteran Art Peck, under whom sales of the company's eponymous brand have tumbled due to out-of-fashion styles and competition from retailers like Abercrombie & Fitch and Europe's H&M.

Here are some quick facts about Fisher:

** This is not the first time Fisher has been interim Chief Executive Officer, having held the role for about half of 2007 following the departure of Paul Pressler.

** Joined Gap in 1980 as a store manager and has since held roles including chief financial officer and chief operating officer of Gap Inc, president of Banana Republic and President of the GAP brand.

** Fisher, a Stanford and Princeton alum, is Gap's largest shareholder with a 12.5% stake, according to Refinitiv data.

** A San Francisco native, Fisher also serves on California's Strategic Growth Council.
