Hubbard trained with J.R. Penniman.[5] From 1822 to 1823 Hubbard formed a business partnership with ornamental and sign painters Samuel Curtis and B.B. Curtis as "Curtis's & Hubbard" (also known as "Curtises & Hubbard"). They produced a variety of painting, "in a plain and neat, or rich and ornamental style as may be requested," including "military standard, plain and ornamental sign, fancy, masonic, landscape, glass, clock and timepiece dial; designs and drawings for cards, diplomas, &c; transparencies ... for window curtains."[6][7] Clients included the Ancient and Honorable Artillery Company of Massachusetts;[8] the Chester Light Infantry of Chester, New Hampshire;[9] and the Haverhill Light Infantry Company of Haverhill, Massachusetts.[10]
He joined the Ancient and Honorable Artillery Company of Massachusetts in 1822. "He was an ensign of a company in the 2nd Regiment, 3rd Brigade, 1st Division, M.V.M., from 1822-1825, lieutenant of the same from 1826-1828, and subsequently was promoted to be captain."[8]
In 1823 he contributed to the July 4th festivities in Hingham, Massachusetts. "The dawn of this interesting day was, as usual, ushered in by the ringing of bells. ... At an early hour a numerous collection of beauty and fashion, alive to the feelings of which the occasion inspired, assembled to witness the presentation to the Hingham Rifle Company, of an elegant stand of colours, painted by Mr. Charles Hubbard, of Boston, in a style which does great credit to the talents of the artist."[11]
Hubbard married Amelia Jane Ripley in 1826; they had several children, including Charles Hubbard Jr. (b. 1835).[12]
