The chairman of Israel’s Yad Vashem Holocaust Museum and Memorial said Sunday he will be stepping down after 27 years.

Avner Shalev, 81, said in a letter to Yad Vashem employees that he made the decision to leave the position after nearly three decades following “thorough self-examination.”

He said he was stepping down by the end of year and gave no further details on his reasons for leaving.
