This very modern-looking portrait depicts Jules Janssen (1824-1907), astronomer, physicist and friend of Henner. It is a study on blue paper, enhanced with oil paint, for a portrait executed in 1879.
Henner and Janssen were very close friends, as evidenced by the abundant correspondence preserved at the museum. They saw each other almost every week for lunches or dinners, in Paris or Meudon, until the end of their lives.
