German baron and connoisseur; friend of museum director Gustav Friedrich Waagen. Liphart and Waagen introduced Wilhelm Bode, later director of the Berlin museums, to the writing of Karl Friedrich von Rumohr. Together, Bode and Liphart were responsible for may re-attributions. In 1871, they independently recognized the similarities between etchings of Hercules Segers (c. 1589-c.1638) and a painting in the Ufizzi, establishing for the first time that Segers was a painter as well.
