Rabbi Yoffey wrote three books. I have previously written about the first, Knesset Yisroel, published in 1910. The second was Tehiyas Yisroel, published in 1927. The third was this book, Shofar Yisroel.
Rabbi Israel Jacob Yoffey was born in Wilkomir (Ukmerge) in Lithuania in 1874. His father-in-law Rabbi Joseph Yoffey had immigrated to England in 1893 and was appointed Rabbi of the Central Synagogue in Manchester. Rabbi Joseph Yoffey died in 1897 and Rabbi Israel Jacob Yoffey succeeded him at the young age of 23. He founded the Manchester Yeshivah and together with Rabbi H. Hurwitz of Leeds he organized a conference in England of eastern European rabbis, in 1911. He was a member of the Manchester Board of Shechita and a supporter of Yeshivos, a religious Zionist, and one of the leaders of the Mizrachi movement.
Rabbi Yoffey died of pneumonia, aged 60, in Alexandria, Egypt, on his way to Palestine.
Rabbi Yoffey starts his book with an introduction:
