The Open Siddur Project is a volunteer-driven collaboration between folk passionate about Jewish spiritual practice. Some are interested in the Siddur as a technology for preserving and disseminating an evolving history of Jewish ritual, practice, and sacred poetry. Others are energized by the design challenge of crafting Siddurim that function effectively for nurturing spiritual, emotional and creative intelligence. All of us see the potential that creative engagement holds for empowering students and teachers to take ownership of those ingredients comprising their shared cultural inheritance.

The Open Siddur is a non-prescriptive, non-denominational project whose only intent is to help revitalize Judaism by ensuring its collective spiritual resources — the creative content intended for communal use — remain free for creative reuse. The Open Siddur Project invites participation without prejudice towards ethnic heritage, skin color, nationality, belief or non-belief, sex, gender, sexuality or any other consideration. All we ask for is an intellectually honest commitment to the principles and sensibilities preserved in our mission statement.

The latter goal was realized in 1952 with the establishment of the Cantors Institute at the Jewish Theological Seminary of America. This Institute later developed into the H. L.

Romi Cohn
Avraham Hakohen Cohn — Romi was a nickname he adopted in America, and he was usually called Rabbi Cohn — was born in Pressburg, now known as Bratislava, the capital of what is now Slovakia, on March 10, 1929. He was one of seven children. When the Germans marched into Czechoslovakia and deported Jews to concentration camps, his family managed to spirit him across the border to Hungary. His mother, two brothers and two sisters perished in the camps. He studied at a Hasidic yeshiva until 1944, when the Germans occupied Hungary and deported tens of thousands of Jews to Auschwitz. He managed to slip back into Czechoslovakia and joined up with a partisan brigade battling the retreating Germans. With the German defeat, Mr. Cohn rejoined his father and two sisters in Pressburg. After the war, Mr. Cohn made his way to the United States and became wealthy developing thousands of single-family homes on Staten Island. He also turned himself into an expert mohel, performing thousands of circumcisions and writing scholarly articles. He even set up an operating theater in his Staten Island home to circumcise adult Russian Jews who had not been able to undergo the ritual as infants because of Soviet strictures. He described his wartime experiences in an autobiography, The Youngest Partisan published in 2001. (via his obituary in the New York Times)
