Sam Roberts, reporting for The New York Times:

David Lerner, a high school dropout and self-taught computer geek whose funky foothold in New York’s Flatiron district, Tekserve, was for decades a beloved discount mecca for Apple customers desperate to retrieve lost data and repair frozen hard drives, died on Nov. 12 at a hospital in Manhattan. He was 72. [...]

Tekserve specialized in finding the cures for sick computers — including insect infestations — and recovering first novels and other priceless data, which the company said it was able to do about 85 percent of the time.

“We only charged for success,” Mr. Lerner said.

There were many great independent Apple resellers from the pre-Apple-Store era. There was only one that was legendary: Tekserve.
