Autographed view of this important officer who served in two famous Regiments the Harvard Regt and the 54th Mass of Robert Gould Shaw.  "Norwood Penrose "Pen" Hallowell (April 13, 1839 – April 11, 1914) was an officer in the Union Army during the American Civil War. One of three brothers to serve with distinction during the war, he and his brother Edward Needles Hallowell both became commanders of the first all-black regiments. He is also remembered for his close friendship with and influence upon future Supreme Court justice Oliver Wendell Holmes Jr., who was his classmate at Harvard and his comrade during the war.Contents1 Background and education2 Civil War service3 Later life4 Death and legacy5 Writings6 Notes7 ReferencesBackground and educationHallowell was born in Philadelphia, Pennsylvania in 1839 to Morris Longstreth Hallowell, and Hannah (Penrose).[1] Norwood and his brothers, Edward Needles and Richard Price, were raised in a household that was strongly Quaker, and strongly abolitionist; during the Civil War, their father opened his home as a hospital for wounded Union soldiers.[2] He was named for his ancestor Captain Bartholomew Penrose Sr. (1674-1711), who settled in the city of Philadelphia in 1698, establishing a shipyard at the invitation of William Penn that stayed in the Penrose family for 150 years. He attended Harvard College, where he befriended Oliver Wendell Holmes Jr. He graduated in 1861 and was elected the Class Orator.[3] Their sister Anna Hallowell was a nurse during the Civil War and went on to be an education reformer.[4]Civil War serviceHallowell's fervent abolitionism led him to volunteer for service in the Civil War, and he inspired Holmes to do the same.[5] He was commissioned a first lieutenant on July 10, 1861, joining the 20th Massachusetts Volunteer Infantry with Holmes.[6] Hallowell fought in the Battle of Ball's Bluff on October 21, 1861, in which he distinguished himself by leading a line of skirmishers to hold off Confederate forces. Hallowell then swam across the Potomac River, constructed a makeshift raft, and made several trips to the Virginia bank to rescue trapped Union soldiers before his raft fell apart.[7] Hallowell was promoted to captain on November 26, 1861.[8] He was wounded in the Battle of Glendale on June 30, 1862, and suffered more severe wounds in the Battle of Antietam on September 17.[9] His left arm was shattered by a bullet but later saved by a surgeon; Holmes was shot in the neck. Both took refuge in a farmhouse (a historic site now known as the Royer–Nicodemus House and Farm) and were eventually evacuated.[10]On April 17, 1863, he was promoted to lieutenant colonel, as second-in-command (after Colonel Robert Gould Shaw) of the 54th Massachusetts, one of the first all-black regiments in the U.S.[11] In a letter to the governor of Massachusetts, John Murray Forbes recommended Hallowell for the promotion based on his bravery, soundness of mind, and willingness to lead a black regiment despite the fact that many found the idea "unpopular."[12] On May 30, he accepted Governor John A. Andrew's personal request that he be made colonel in command of the 55th Massachusetts, another all-black regiment.[13] He and his regiment were stationed at Charleston Harbor and participated in the siege and eventual taking of Fort Wagner; Hallowell was one of the first to enter the fort after its abandonment.[14] Hallowell faced continuing disability due to his wounds, and was discharged on November 2, 1863."
