Notwithstanding his work in many fields, his real interest was always in modern law. He has been called an antiquarian, but his studies in this line did not go beyond colonial history, more particularly Connecticut history. Few men have played a more important part in so many activities that concerned their own community. When he was presented for the degree of LL.D. at the Yale Commencement in 1916 he was called, inter alia, ""the first citizen of Connecticut."" No designation could have fitted him better. ―George Edward Woodbine   He was the son of Roger Sherman Baldwin, brotherin-law of Dwight Foster (1828–1884), uncle of Edward Baldwin Whitney, grandson of Simeon Baldwin, and the great-grandson of Roger Sherman. [Good likenesses of Baldwin in his later years in "American Bar Association Journal", February 1927, p. 73, and in "Yale Alumni Weekly", February 11, 1927, p. 555; for an estimate of the man and his achievements see the articles accompanying these and also "Yale Law Journal", March 1927, p. 680; "New Haven Journal-Courier", "Hartford Times", "Hartford Courant", January 31, February 1, 2, 1927; "Who's Who in America, 1899–1927". There is a complete list of his writings in Yale University Library; partial lists, together with considerable biog. material, are given in the records of the class of 1861, Yale College, published by the class secretary, especially those for the years 1888, 1903, 1907, 1916. His legal bibliography, fairly complete through 1901, was printed in "Yale Law Journal", November 1901, pp. 14–16. His opinions and decisions written while he was on the bench will be found in Conn. Reports, volumes LXIII-LXXXIII. For the facts in regard to his controversy with Roosevelt, see Outlook, volume XCVII, Jan. 1911, pp. 240–244.
