Johan Linder

Johans Linder (1678 - March 24, 1724) was a Swedish botanist and medical doctor who was later ennobled as Lindestolpe.

[1] He wrote a book about natural dyes and their sources including plants, insects, and minerals.

[2] He was born 1678 in Karlstad, Sweden and went to university in Uppsala with his first thesis titled De pomis hesperidum ("On the Apple of the Hesperides") in 1702.

[1] He defended a second thesis in 1705 titled De Foeda lue venerea dicta translated in 1713 into Swedish as Tankar om then smittosamma sjukom franzoser ("Thoughts about the very infectious French disease syphilis").

[1] He encouraged other doctors to aid those inflicted with syphilis, rather than embarrass then with "moral preaching", although at the time there was little they could do to help.
