H. Frederick Day, a well known figure in legal and in insurance circles of New Haven, was born in Hartford, Connecticut, May 10, 1888, a son of Frederick Ellsworth and Sidonie (Neuricel) Day. He acquired a public school education in Hartford and afterward attended the Episcopal Academy at Cheshire and was graduated from the Hartford high school with tlie class of 3906. His law course was pursued in Vale and he was graduated from the legal department in 1911. He was afterward connected with the legal department of the Minneapolis & St. Louis Railroad at Minneapolis for a year and a half and subsequently spent a similar period in connection with the legal department of the Minneapolis, St. Paul & Sault Ste. Marie Railroad Company. On the expiration of that period he went to New York and accepted the position of assistant attorney with the Hartford Accident & Indemnity Company. In May, 1916, he removed to New Haven, where he was acting as attorney for the same company until June, 1917, when he resigned this position to practice for himself, having been admitted to the bar of Connecticut in 1911.

On the 20th of October, 1909, Mr. Day was united in marriage in Boston, Massachusetts, to Miss Doris H. Hosmer, originally from Providence, Rhode Island, but living in Brookline, Massachusetts, at the time of her marriage. They have become the parents of three children, Marion, John Marshall, born November 2, 1913, and Gwendolen.

Mr. Day is a member of Nu Sigma Nu and also belongs to the Masonic fraternity. He is a vestryman of Christ's Episcopal church of East Haven and thus takes active and helpful interest in promoting the moral interests of the community with which he is now identified. His political endorsement is given to the men and measures of the democratic party. In military circles he is well known, serving as second lieutenant of Company M of the Home Guard of New Haven, having enlisted in 1917. Previously he had been a private of Company K of the First Connecticut Infantry and passed the examination that won him the commission of lieutenant. He is a young man thoroughly in earnest in all that he does, actuated by a patriotic devotion to the general good that prompts him to uphold the highest civic standards as well as support the policy of the country in days of war.
