He studied art in New York City from 1822 to 1824, teaching himself drawing and painting before departing to study in Italy in 1824.[8] He remained in Florence from 1824 to 1825, then in Rome from 1825 to 1827, during which time he studied the works ofMichelangelo,Raphael, and other Italian masters of theRenaissance. He returned to New York in 1827 to care for a sick friend and remained there until 1834, becoming an integral part of its artistic community. He was appointed as Teacher of Drawing (1834–1846) then Professor of Drawing (1846–1876) at theUnited States Military Academy atWest Point, New York.[2][9]
Weir was the fifth artist to hold the position of art instructor at the academy.[10] During his 42 years (1834–1876) in this post, he instructed many of the future commanders of theAmerican Civil War. Among his notable students at West Point wereJames Abbott McNeill Whistler andSeth Eastman. He also developed a special relationship withUlysses S. Grant.[9] He died in New York City on May 1, 1889.[10]

He was commissioned by theUnited States Congress in 1837 and the painting was placed in the rotunda in December 1843.[13] His canvases deal principally with historical subjects, though he also did several portraits.
