George Barry O'Toole, OSB (1886 – 26 March 1944[1]) was an American Catholic priest and activist.
He began his religious career as a parish priest and as a U.S. Army chaplain in World War I.
He was a founding member of the Catholic Radical Alliance, an early labor support organization in Pittsburgh, Pennsylvania, and was important to the foundation of St. Joseph's House of Hospitality, also in Pittsburgh.
O'Toole was the author of the creationist book The Case Against Evolution (1925).
[5] Science writer Martin Gardner noted that O'Toole endorsed the "naive criticism of strata chronology" from creationist George McCready Price.
