Max Jessner (2 November 1887 – 27 August 1978)[citation needed] was a German dermatologist and university professor.

[2][5][6] For post-revolutionary Russia, the expedition marked an opportunity to use science to solidify political relations and improve communication.

[4] Biberstein later became professor of dermatology at New York University[4] like many other dermatologists who escaped Nazi-occupied Europe by travelling to North America.

[4] Also known as the Coombe's formula,[12] Jessner developed it to form Jessner's solution,[13] a liquid peeling treatment for hyperkeratotic epidermal lesions, containing salicyclic acid, resorcinol, and lactic acid in 95% ethanol, and works by breaking intracellular bridges between keratinocytes.

[15] It was here that in 1953, with Kanof, he became renowned for the description of Jessner-Kanof disease, a lymphocytic infiltrate of the skin where the lesions were asymptomatic, presenting as red spots or plaques with spontaneous recurrences.
