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: According to the Lexikon der Düsseldorfer Malerschule [Lexicon of the Düsseldorf School of Painting], 1998, provided by Kathrin DuBois, Acting Head of the Gallery of Paintings at Kunstpalast Düsseldorf, Johnson enrolled formally in only one class as a student at the Düsseldorf Academy: Anatomy and Proportion with Professor Heinrich Mücke, winter 1849–1850. This sketchbook contains his precise sketches and notations, including ideal proportions for the human body, that indicate a new level of sophistication in his drawing. Johnson also made a sketch of Professor Mücke (1806-1891), who was a painter, draftsman, and printmaker of religious and genre scenes.
