He is a Jewish cultural historian whose work has been devoted to the intersections of Kabbalah, magic, and science in the early modern period. In the last decade, he has become the leading scholar of visual Kabbalah, having founded The Ilanot Project and published the first major work on the previously unstudied genre of ilanot (scrolls featuring the arboreal diagram commonly known as the "Tree of life"). He is the author of Between Worlds: Dybbuks, Exorcists, and Early Modern Judaism and The Kabbalistic Tree. In 2013, he was elected to the Executive Board of the World Union for Jewish Studies, where he serves as Division Chair for rabbinic literature, Jewish law, and Jewish thought.

Life and education

J. H. Chajes was born in Detroit, Michigan (USA) to the composer and pianist Julius Chajes and the mezzo-soprano, Annette Schoen Chajes. Chajes studied piano with his father and, for three years beginning at the age of eleven, performed piano concerti annually as a soloist with the Center Symphony Orchestra under his father's direction.

Chajes completed his B.A. in Jewish Studies at the University of Michigan in 1988 and an M.A. in history at the same institution in 1989. After serving for a year as the first volunteer Jewish educator sent by the American Jewish Joint Distribution Committee to Mumbai (then Bombay), India and studying Talmud for another year in Jerusalem at a traditional yeshiva, he was awarded a Wexner Graduate Fellowship to embark upon doctoral studies at Yale University. His doctoral thesis, Spirit Possession and the Construction of Early Modern Jewish Religiosity (1999), was supervised by David B. Ruderman.

Chajes was a Fulbright Visiting Research Fellow at the Hebrew University in 1995-96 and a Yad haNadiv Post-Doctoral Fellow at the same institution in 1999. From 1996 to 1999 he was also a Research Fellow at the Shalom Hartman Institute in Jerusalem. Chajes has been a visiting professor at the Jewish Theological Seminary in New York, a three-time fellow at the Katz Center for Advanced Judaic Studies at the University of Pennsylvania, and a fellow at the Israel Institute for Advanced Studies in Jerusalem and the Forschungskolleg Humanwissenschaften of Goethe University Frankfurt.

Scholarship

Chajes leading the Lehmann Memorial Master Workshop on the History of the Jewish Book, University of Pennsylvania (2019)

Chajes's research focuses on the intersection of Kabbalah, magic, and science in Jewish cultural history. He has written on spirit possession and exorcism, egodocuments, women's religiosity, Jewish attitudes towards magic, and, most recently, on the visualization of knowledge. Chajes's first book, Between Worlds: Dybbuks, Exorcists, and Early Modern Judaism (2003) was listed by the Wall Street Journal as among the top five books ever written on spirit possession, alongside Aldous Huxley's The Devils of Loudun. Chajes's foundational book, The Kabbalistic Tree, published in November 2022, has been lauded as a "monumental achievement that will be valuable to scholars and general readers interested in Judaism, religion, and art history."
