(JTA) – Rabbi Aaron Panken, the president of Hebrew Union College, was killed piloting a small aircraft in the Hudson Valley area of New York state. The plane crash occurred in a wooded area in the Town of Wawayanda, near the New Jersey border Saturday, April 28. A passenger, Frank Reiss, a flight instructor, was injured. Panken was 53 and a licensed commercial pilot.

Panken had led the Reform movement’s flagship seminary since 2014. Prior to serving as the chief executive officer of HUC’s four campuses – in Cincinnati, Jerusalem, Los Angeles and New York – the native New Yorker held senior positions at the school, including vice president for strategic initiatives, dean of the New York campus and dean of students. He was ordained in 1991.

The HUC release called Panken an “ardent supporter of Reform Judaism in Israel.”

In a 2015 op-ed for JTA decrying the perceived growth of fundamentalism in Israel, Panken said the Reform movement had an important role to play in advancing pluralism in Israel.

“Israel is a leader in technology, education, health care and more,” Panken wrote. “It should now strive to become a leader in religious pluralism and to embrace Reform Judaism as ardently as Reform Jews embrace Israel.”

Panken grew up on Manhattan’s Upper West Side, was ordained by HUC, worked as an associate rabbi at Manhattan’s Congregation Rodeph Shalom and earned a doctorate in Hebrew and Judaic Studies at New York University. He also had a degree in electrical engineering from Johns Hopkins University.

Taking over at HUC in 2013, he told JTA that he intended to recruit the “best and brightest” to careers in the rabbinate.

“I’d love to see more people who have had significant and meaningful Jewish experiences actually consider these careers,” Panken said. “Unfortunately, for a lot of young folks it’s not the first thing people are talking about as a career choice.

“I’d like it to become more of a household term that people really think about. It’s important for us to remind them about the great possibilities. The rabbi/cantor/educator who was so inspiring for you as a young person – you can be that person.”

Tributes to Panken appeared on Twitter within hours of the news. Israel’s consul general in New York, Dani Dayan, said the rabbi had hosted him less than a month ago at HUC. “A great thinker,” said Dayan. “A huge loss for the entire Jewish people.”

Dan Shapiro, the former U.S. ambassador to Israel, remembered Panken as a “brilliant Jewish leader, an incredible mensch and a dear friend.”

Panken was to have presided over the ordination of rabbis and cantors at ceremonies in New York on Sunday, May 6. This year the seminary will ordain 28 rabbis at three campuses, and six cantors.

Panken is survived by his wife, Lisa Messinger, his children Eli and Samantha, his parents Beverly and Peter, and his sister, Rabbi Melinda Panken of Congregation Shaari Emeth in Manalapan, N.J.
