James Jackson Storrow II (January 1864[Note 1] – March 13, 1926) was an American investment banker, government official, and scouting leader.

Active in public life, Storrow was a member of Boston's city council and school committee and lost a close race for Mayor in 1910.

[6][5] Helen Storrow became a prominent international Girl Scout leader, and both became known for social activism in Boston and New England.

[2][3] The firm handled legal affairs for Lee, Higginson & Co. and in 1900, Storrow was persuaded to leave his law practice to join the investment bank as a partner.

[6] In 1910, Storrow led a group of financiers organized as a voting trust who wrested control of General Motors from that corporation's founder Billy Durant.

[8] On January 26, 1911, he was elected chairman of the finance committee, which had full control over the company's fiscal affairs, and was succeeded as president by Thomas Neal.

[3][15] He was reportedly under consideration to succeed Charles William Eliot as President of Harvard University, however he denied having interest in the position.

Unlike many of his Boston Brahmin peers, Storrow rejected nativism and anti-Catholic, anti-Semitic and anti-immigrant prejudices.

[19] Storrow faced opposition from some of Boston's powerful influences, including the city's chamber of commerce; however, the Massachusetts legislature approved the dam in 1903.

[3][19] The Boston Globe crediting Storrow's "hard work, influence and speeches before the legislature" for the bill's passage.

[20] Due to November voting on the proposed charter change, the 1909 mayoral election was pushed back to January 1910.

[22] The Citizens' Municipal League was made up mostly of Republicans, but Storrow was able to secure the endorsement of Democratic city committee president James Donovan and Congressman John A.

[27] In 1919, Boston faced a possible strike by its police officers who were seeking the right to form a union under a charter from the American Federation of Labor.

Storrow's group recommended that the police be allowed to form their own union, but that it should be independent and not affiliated with any other organization like the AFL.

[29] He ran for a full three-year term that November and received the most votes of the eight candidates running for the three council seats.
