Israel Zangwill (1864-1926) was a British writer. Born in London, Zangwill was raised in a family of Jewish immigrants from the Russian Empire. Alongside his brother Louis, a novelist, Zangwill was educated at the Jews' Free School in Spitalfields, where he studied secular and religious subjects. He excelled early on and was made a teacher in his teens before studying for his BA at the University of London. After graduating in 1884, Zangwill began publishing under various pseudonyms, finding editing work with Ariel and The London Puck to support himself. His first novel, Children of the Ghetto: A Study of Peculiar People (1892), was published to popular and critical acclaim, earning praise from prominent Victorian novelist George Gissing. His play The Melting Pot (1908) was a resounding success in the United States and was regarded by Theodore Roosevelt as "among the very strong and real influences upon [his] thought and [his] life." He spent his life in dedication to various political and social causes. An early Zionist and follower of Theodor Herzl, he later withdrew his support in favor of territorialism after he discovered that "Palestine proper has already its inhabitants." Despite distancing himself from the Zionist community, he continued to advocate on behalf of the Jewish people and to promote the ideals of feminism alongside his wife Edith Ayrton, a prominent author and activist.

In the eighteenth century, when "England denied her Jews every civic right except that of paying taxes," a class Schnorrers, or beggars, is forced through desperation to survive by the charity of others. Confronted by one of these men, Joseph Grobstock makes the biggest mistake of his life. The King of Schnorrers is a novel by Israel Zangwill.
