...he made a translation of George Christian Knapp's Christian Theology, which became long used as a textbook in American theological seminaries. When he became president of Bowdoin in 1839, he was only 32 years old. He held his position until 1866. During his tenure, the College built Appleton Hall, the Chapel, and Adams Hall, which housed the Medical School of Maine and the undergraduate laboratories. A recipient of advanced degrees from Colby College, Harvard University, and Bowdoin, Woods died in 1878 in Boston, Massachusetts.
