(1850 – 1929)
The most famous freelancer in company history and the most well-known and important dermatologist of his time was born in 1850 in Hamburg. After he graduated from high school, Unna studied medicine at the Universities of Heidelberg, Leipzig and Straßburg. In 1881, he opened a private dermatological clinic on Dammtorstraße in Hamburg. At this time, he first met Paul C. Beiersdorf, in close collaboration with whom he developed a process for the manufacture of coated plasters – the very product on which our company was founded in 1882.
