Early life and ancestors
He was a grandson of Jesse Ladd and Ruby Brewster, who were among the original pioneers in Madison, Lake County, Ohio. Ruby was a granddaughter of Oliver Brewster and Martha Wadsworth Brewster, a poet and writer, and one of the earliest American female literary figures.
He was a descendant of Elder William Brewster (c. 1567 – April 10, 1644), the Pilgrim leader and spiritual elder of the Plymouth Colony and a passenger on the Mayflower, and Governor William Bradford (1590–1657) of the Plymouth Colony and a passenger on the Mayflower. He was also a 7th generation direct lineal descendant of Daniel Ladd, Sr. (1613–1693).
He early gave indications of the studious habits that characterized him through life. When he was eight years old his first savings, two dollars, were spent for a copy of Josephus and Plutarch, while when eighteen years of age he read Kant's Critique of Pure Reason.
Most of his work in preparing for college was done by himself, only a portion of the time being given to the curriculum in the Painesville High School and at the college preparatory school of the Rev. Mr. Brayton in Painesville, Ohio.
He graduated from Western Reserve College in 1864 and from Andover Theological Seminary in 1869. He was ordained to the Congregational ministry on May 26, 1870. The degree of Doctor of Divinity (D.D. or DD, Divinitatis Doctor in Latin) was conferred on him by Western Reserve College in 1879; Yale University that of M.A. in 1881, Western Reserve College that of LL.D. in 1895, and Princeton University that of LL.D. in 1896.
After graduation, he went into business with his father. His constant studies, however, seemed to turn his steps naturally toward a higher institution of learning, with the result that in 1866 he went to the Andover Theological Seminary.
In 1869, he was installed as the pastor of the Congregational Church in Edinburg, Portage County, Ohio, remaining here until 1871. In 1871 he began to preach at the Spring Street Congregational Church of Milwaukee, Milwaukee County, Wisconsin leaving in 1879. He was professor of intellectual and moral philosophy at Bowdoin College from 1879 to 1881, and Clark professor of metaphysics and moral philosophy at Yale University from 1881 until 1901, when he took charge of the graduate department of philosophy and psychology; he became professor emeritus in 1905. He retired in 1906.
Between 1892 and 1899, at the invitation of the Government of Japan, he served as a diplomatic adviser and helped the Cabinet under Prime Minister Hirofumi Ito (1841–1909) to promote mutual understanding between Japan and the United States.
The series of lectures he delivered in Japan revolutionized its educational methods; In 1899, Emperor Meiji conferred the Order of the Rising Sun, Gold Rays with Neck Ribbon, which represents the third highest of eight classes associated with the award. Trumbull was again honored in 1907, this time with the Order of the Rising Sun, Gold and Silver Star, which represents the second highest of eight classes. He was the first foreigner to receive the honor in this class.
He was much influenced by the German philosopher Hermann Lotze, whose Outlines of Philosophy he translated (6 vols., 1877) and was one of the first to introduce (1879) the study of experimental psychology into America; the Yale psychological laboratory being founded by him. In 1887, he published Elements of Physiological Psychology, the first American textbook to include a substantial amount of information on the new experimental form of the discipline.
Marriage and family
He married on December 8, 1869 at Bridgeport, Belmont County, Ohio, Cornelia Ann Tallman, born August 26, 1842 at St. Clairsville, Belmont County, Ohio and died on October 19, 1893 at North Haven, New Haven County, Connecticut. She was the daughter of Ellen Ryne and John C. Tallman, a well-known banker and business man of Bridgeport, Ohio.
George and Cornelia were the parents of four children:
- George Tallman Ladd (1871–1943), an Industrialist of Pittsburgh, Pennsylvania and an 1891 graduate of Yale University. He was president and CEO of United Engineering & Foundry Company, the largest U. S. maker of steel mill equipment. The George Tallman Ladd Award, at the Carnegie Institute of Technology is named after him.
- Dr. Louis Williams Ladd, (1873 - 1955), was a doctor of internal medicine and professor of clinical microscopy at the Case Western Reserve University School of Medicine. He graduated from Yale University in 1895 earning his Bachelor of Arts degree, and he graduated with an MD from Johns Hopkins University School of Medicine in 1899.
- Jesse Brewster Ladd, (1876–1882).
- Elizabeth Tudor Ladd, (1882 - 1965), married Walter Aldrich Barrett.
He married second, on December 9, 1895, Frances Virginia Stevens, born February 9, 1866 at New York City, the daughter of Dr. George T. Stevens and Harriet Weeks Wadhams. There were no children from the second marriage.
Ladd died on August 8, 1921 at New Haven, Connecticut. After cremation, half his ashes were buried in a Tokyo Temple and a monument was erected to him. The remaining ashes were interred under a monument of the rising sun in Grove Street Cemetery, New Haven, Ct.
