Jewish History: The Great Rabbis: Rabbi Yitzchak of Acco:
Who was Rabbi Yitzchak of Acco?
R.Yitzchak (b.Shemuel) of Acco was born in Eretz Yisroel in 1250 C.E.
When Acco was conquered by the Egyptians in 1299 he apparently
remained in the area, but in 1305 he was in Italy, and afterwards he
settled in Toledo, Spain, where he died in 1340.
He was the author of several Kabbalistic works; some of them still
exist in manuscript, but none of them have been published yet. He
is well known for his visits to R.Mosheh de Leon, and afterwards to
his widow, in an unsuccessful attempt to discover a manuscript source
for the Zohar, which R.Mosheh was circulating.
