Becoming the head chef of a 16th-century monastery library (thus its name), Jonnie Boer started his prestigious career at De Librije in 1989, when he was just 24. In 1992, he bought the restaurant with his wife, Therese, and he earned his first Michelin star the following year.

When he won his second star in 1999, he was the youngest two-star chef in The Netherlands. In 2004, it was the second Dutch restaurant to ever be granted a third star. The following year, Boer was knighted.

He followed up De Librije with Librije’s Zusje, which earned a star within six months of opening and a second star in 2011.
