NEW YORK — Michael Rosenzweig still step down this summer as president and CEO of the National Museum of Jewish History.

Rosenzweig, who has led the Philadelphia museum since April 2009, will be succeeded by Ivy Barsky, according to a news release. Barsky, who joined the Philadelphia museum in 2011, is a former deputy director of the Museum of Jewish Heritage-A Living Memorial to the Holocaust in New York and has worked at museums for more than a decade.

“I am gratified to have this opportunity to work with the board and staff to take the museum to the next level as a regional and national asset,” Barsky said. “My goal is to bring to life — in the way we operate as a museum and in how we serve our audiences — the spirit of optimism, willingness to take risks, and dedication to making a better world, which are embodied in the stories of American Jewish history.”

The National Museum of Jewish History opened in November 2010 following a $155 million capital campaign.
