I bought this book from M. Rogosnitzky, the Hebrew Bookseller of Golders Green. It is a large sized book, beautifully printed in London at the Brill Press and bound in the original impressed cloth with gold leaf edges to the pages. I have previously written about another book by Dr. Wigoder, written a little later, Keter Torah. You can read about it here.
Dr. Selig George Wigoder, or, to give him his full name, Chaim Yehoshua Zelig, the son of Yehuda Leib Wigoder, was born in the town of Wegoda, near Wexna, Lithuania, in 1865. He studied Philosophy and then Medicine in Halle, Germany and later Medicine in Edinburgh. He joined his brother Myer Joel Wigoder who had emigrated to Dublin, Ireland. On August 7th, 1895, he married Jessie Bradlaw, in the Adelaide Road Synagogue in Dublin. Selig and Jessie had a son, Lionel, born on the first day of the month of Av, but Selig was actually away in Edinburgh, studying for his final medical examination. He returned to Dublin two days later as a qualified medical doctor who could practice in Dublin.
As well as becoming a prominent doctor in Dublin, Selig was a prolific author in Hebrew (as was his brother Myer Joel Wigoder). His works included Keter Torah, dedicated to his late mother-in-law, and Beth Avigdor, dedicated to his late father-in-law.
This book was published ten years after his marriage, by which time he was established as a successful doctor in Dublin.
Beth Avigdor is dedicated to Dr. Wigoder’s late father-in-law, Robert Bradshaw of Dublin:
This book starts with some interesting haskamos, or approbations from other Rabbis.
- Rabbi Eliyahu Boruch Kamai of the Mir Yeshiva, the grandfather of Rabbi Eliyahu Boruch Finkel, who was an influential maggid shiur (lecturer) at the modern Mir Yeshiva in Jerusalem.
- Rabbi Shlomo Mordechai Brodna, Rabbi of Stowbtsy, near Minsk.
- Rabbi Mordechai Koppelowitz of Krasnow.
- Rabbi Isaac Meir Joselson, Chief Rabbi of Dublin.
- Rabbi Aaron Leib Glikman of Dublin.
In the introduction, Dr. Wigoder shares some details of his life story:
A few words from Rabbi Aaron Leib Glikman of Dublin:
A contribution from Dr. George Wigoder’s brother, Rav Meir Yoel Wigoder. Myer Joel Wigoder was the grandfather of the British Liberal Peer, Lord Basil Wigoder, and of the historian and editor of the Jewish Encyclopedia, Geoffrey Wigoder.
And a final page:

Rav Elya Baruch Kamai and Rav Brudna and the other Eastern European rabbis who wrote letters of approbation mention that they are relatives. But no details. Any genealogy information?
