26 May 1811–19 Apr. 1868
His first parish was at Saugerties, N. Y. In February 1837 he became the first rector of Trinity Church, Buffalo, N. Y., and in October 1843 he accepted a call to Christ Church, St. Louis, Mo. The next year, on 20 October, during a General Convention at Christ Church, Philadelphia, he was consecrated as the first Episcopal bishop of the new Diocese of Missouri.
As a pioneering missionary on the western frontier, Hawks labored tirelessly through a wide area, traveling by horseback, wagon, stagecoach, and steamboat. For ten years he was also rector of the St. Louis church until the diocese was able to assume his support. When that city was scourged by an epidemic of Asiatic cholera in 1849, he remained heroically at his post, ministering to the sick and burying the dead.
Throughout the twenty-five years of his bishopric, Hawks traversed the entire state, conducting services, organizing parishes, and winning friends for himself and his church by his attractive personality, eloquent sermons, and dedicated devotion to his calling. Even during the Civil War he continued his arduous journeys, carrying consolation to grieving homes and trying to bind up the wounds of civil strife. "I hope all my flock go to church now," he wrote, in his earnest efforts to "harmonize all elements in the church."
Having taken the earlier oath of loyalty to the Union, Hawks advised other clergymen to decide according to their own consciences whether or not to take the postwar "Ironclad Oath," though he deplored some of its features. In those stormy times his health began to fail. Weak from his labors, he held an Easter Sunday service in 1868 at St. Louis with the assistance of a visiting minister. A week later he died, and was buried in Bellefontaine Cemetery, St. Louis.
On 19 Feb. 1835 in New Bern, Hawks married Anne Jones, daughter of Dr. Hugh Jones and Anna Maria Guion, and a great-niece of Governor Benjamin Williams.
