Here’s Reuters with the report:

Donald Fisher, who co-founded Gap Inc (GPS.N) with his wife Doris forty years ago, died on Sunday after a battle with cancer, the clothing retailer said. He was 81. The company that the Fishers began as a little denim store in San Francisco now operates more than 3,100 stores in the United States, the United Kingdom, Canada, France, Japan and Ireland, and it has been credited with inventing the specialty retail category.

The Fishers opened their first store in San Francisco in 1969, and named it The Gap in reference to the generational differences between baby boomers and their parents.

When it first opened, the Gap mainly sold Levi’s jeans, tapes and records, and it flourished in 1970s as consumers snapped up its denim.
