Question: What state were the educational institutions that Morison attended located in? Passage:Born in New Bedford, Massachusetts, he was the son of John Hopkins Morison, a Unitarian minister. At age 14, he entered Phillips Exeter Academy and graduated by age 16. He went on to Harvard College where he was a classmate of philosopher John Fiske. Morison received a Bachelor of Arts degree in 1863 when he was just 20. After a brief break he attended Harvard Law School where he would receive a Bachelor of Laws degree by 1866 and was admitted to the New York Bar. In 1867, with only general mathematics training and an aptitude for mechanics, he abandoned the practice of law and pursued a career as a civil engineer and builder of bridges. He would apprentice under the supervision of engineer Octave Chanute during the construction of the first bridge to cross the Missouri River, the swing-span Kansas City Bridge.
