Johnson went to Europe in 1849 to learn techniques for creating figure paintings in oil. However, he had been a professional portrait draughtsman in Boston and Washington, D.C. for at least five years before that. In those early drawings he had a keen sense of creating heads using light tones and shadowed areas to create a strong three-dimensional effect. Studying the works of Rembrandt at The Hague inspired him to use the same techniques for his oil portraits. —PH
