Robuchon's impact on food was so enormous, he was called "cook of the century" back in 1990. One of the things he did that has been enduring ... letting diners have a peek into how his food is cooked and plated. He was the first major chef to make it cool for diners to sit at a counter next to the kitchen.

Robuchon appeared on "Top Chef" and a variety of French cooking shows.

He was the holder of more Michelin stars than any chef in the world for years. As of 2016, he held 32 stars -- his peak. This year he had 31.

Perhaps his signature dish ... puree de pomme -- which you probably know as mashed potatoes. He prepared it simply, but it was amazing.

Robuchon died in Geneva from pancreatic cancer.

Joel was 73.
