Gerry served as vice-president of SPCC, then as Wright's successor from 1879 to 1901, and finally as legal advisor until his death. The Society's deputies, nicknamed "Gerry men" or "the cruelty," aroused controversy by enforcing various laws, including child labor laws concerning public performances and were allowed to remove children from homes. Some criticized their activities as interfering with family life, or for imposing aristocratic white Protestant values upon immigrants, many of whom were Catholic or black.
