Johnson finished his formal schooling at fifteen and worked in a dry goods store where he began making drawings. Responding to his talent, his father sent him to work in a lithography shop in Boston, probably Bufford’s. Several figure and landscape sketches survive from the early 1840s which indicate the ways he was exploring the human figure and the landscape about him using graphite pencil. More importantly, he began to excel as a portrait draughtsman in these early years; see Themes 43.1–.9, U.S. Early Portrait Drawings.
Johnson's reason for his sojourn in Düsseldorf and The Hague, 1849–1855, was to learn to paint with oil (see Themes 1.0–5.0). To achieve that goal, he studied anatomy while still making graphite sketches of interiors, landscapes, and figures from life. Among his best composed sketches were those done on trips to the Dutch countryside, especially those done at Dongen, the Netherlands. —PH
MacGibeny, 2022: As Baur states, Chandler was the maiden name of Johnson's mother. However, Paul Chandler was not her brother. He may have been her cousin (thus Johnson's cousin, once removed) Paul Chandler of New Hampshire (1827–1883).
Baur 1940, p. 30: "Both sides of the paper are covered with numerous small drawings, some of which may have been planned as illustrations for a story. Chandler was the maiden name of Johnson's mother, and Paul was likely one of her brothers."
