Philip Klein (May 22, 1849 – March 21, 1926) was a Hungarian-born rabbi who ministered in the Russian Empire and America.

He spent some time as an instructor at the University of Berlin, and then accepted a position as tutor for the son of Israel Brodsky in Kyiv, Russia.

[3] He then served as Rabbi of Libau, Courland from 1880 to 1890, when he immigrated to the United States due to the growing antisemitic policies in the Russian Empire, which resulted in him being told he would not be reappointed to his rabbinic post.

She served as vice-president of the Women's Branch of the Union of Orthodox Jewish Congregations of America and honorary president of the Sisterhood of Congregation Ohab Zedek, conducted a Talmud Torah in the Lower East Side for over 200 children, and organized the Julie Hirsch Klein Benevolent Society.

Their children were Leo, Samson, Marcus, David, Raphael, Emanuel, Mrs. Harriet Lunzer, and Elizabeth.

Julie Klein grew sick from pneumonia while taking care of her husband, who was dying of the same illness.
