April 23 is the traditional date of the birthday of the Vilna Gaon, the most outstanding scholar of sacred Jewish texts in the modern era. Last year Lithuania was supposed to celebrate his 300th birthday with fanfare, but public events were canceled due to fears for public health.

YIVO’s Encyclopedia of Jews in Eastern Europe says the Gaon, also known by the acronym GRA, was a spiritual giant, an example to future generations, a source of inspiration and the central figure in Litvak culture.
