The stuccoed Colonial Revival house at 301 Prospect Street in New Haven was built in 1907 for Pierce Noble Welch. He was Yale graduate (1862) who then studied in Germany. In 1871 Welch became treasurer of the New Haven Rolling Mill Company, which his father, Harmanus M. Welch, had founded. He later became president of the company and in 1889 he succeeded his late father as president of the First National Bank of New Haven. In 1891, Welch and his two sisters donated Harmanus Welch Hall to Yale. He was also president and a director of the Bristol Brass Company, a director of the Bristol Manufacturing Company, a vice-president and director of the New Haven Gas Light Company, and a director of the New Haven Clock Company. Pierce N. Welch, born in 1841, died in Berlin, Germany in 1909. The house was acquired by Yale in 1935 and served as a dormitory and later as offices. It is currently home to the Yale School of Forestry and Environmental Studies.
