AMSTERDAM — The board of trustees at the Rijksmuseum announced on Monday that Taco Dibbits, the museum’s director of collections, would replace Wim Pijbes as general director. Mr. Pijbes, who had seen the museum through a major expansion, announced his resignation in March after accepting a job as director of a new private museum.

Mr. Dibbits, who has been with the Rijksmuseum since 2002, will assume the post after Mr. Pijbes steps down on July 15.

“It’s one of the most beautiful museums in the world, and it’s a dream come true for me,” Mr. Dibbits said in a telephone interview. “I’ve already got a fantastic team of people, and we hope that we can make as many people as possible enjoy and be inspired, and be touched by, the great works of art that the museum houses.”

Mr. Dibbits, 47, joined the Rijksmuseum 14 years ago as the curator of 17th-century painting, before the museum closed for a decade-long expansion and renovation at a cost of 375 million euros, or about $415 million. “I came in because the museum was going to renovate,” he said, “and I was excited to have a central role in the renovation project.”
