What does "of + company name + fame" mean?

Question

I was doing a Cambridge English Advanced Use of English Part 2 test today, when I came across the following sentence in a text:

The first mass-produced versions, made by Sam Foster _______ Foster Grant fame, were sold in the 1920s in US seaside resorts.

The task is to put one word in the gap. According to the answer key, that's of. I did some research and found out it's a structure that appears with other companies as well: Internet Explorer, Facebook, etc.

Is this a fancy way of saying famous for because I can't find any references to this structure in Cambridge Dictionary or Merriam Webster?

Answer 1

It doesn't have to be only a company name that provides the nature or origin of the fame. Taylor Swift of singing fame, K.C. Gillette of razor blade fame, Buzz Aldrin of Apollo moon shot fame.

Fame noun [uncountable]
the state of being known about by a lot of people because of your achievements
He claims he is not really interested in fame.

of ... fame
(=used to show what someone is famous for)
Muhammad Ali, of boxing fame
