NEW YORK, Sept 24 — A Jewish ram’s horn instrument hidden and blown behind the barbed wire of Auschwitz was shown publicly for the first time yesterday in New York, where it will be included in an exhibition.

The shofar — a wind instrument traditionally used at services during the Jewish High Holidays, whose sound is a call for mercy — was obtained by the former prisoner Chaskel Tydor during a "death march”.

During these marches, Nazis forced prisoners to walk on foot in winter to other camps as Soviet troops encroached.

Tydor survived the Holocaust and moved to Israel before emigrating to the United States.

He kept the shofar until his death in 1993, when it was passed on to his family.

His daughter, Judith Tydor Baumel-Schwartz, presented it publicly yesterday at Manhattan’s Museum of Jewish Heritage.

Nazis forbade all Jewish religious practices in camps under punishment of death.

But according to several accounts, this did not prevent Auschwitz prisoners from using the shofar, which emits a powerful foghorn-esque blast, at great risk to their lives.

"Even for non-believing Jews, this was an act of pure defiance,” said Michael Berenbaum, a curator of the exhibition titled, "Auschwitz. Not Long Ago. Not Far Away.”

"It was blown in Auschwitz precisely because it was forbidden.”

The shofar will go on display at the exhibition that runs until January 3, 2020, having already drawn some 100,000 visitors during an earlier showing in Madrid.

The instrument will also be used in two Manhattan synagogues for Rosh Hashanah, the Jewish New Year, and Yom Kippur, the Day of Atonement. — AFP
