Maria Christina Bruhn ( Swede. Maria Christina Bruhn , 1732-1802) - Swedish inventor, most likely the first of the inventors who patented the invention in Sweden.
Brun was the eldest of the three daughters of bookmaker Johan Brun (d. 1742). She took over the tapestry and wallpaper factory after the death of her widowed mother, Inga Cristina, in 1751.
In 1771, the Royal Swedish Academy of Sciences offered an award to those who could produce a suitable powder package for the army. While working in the manufacture of paint and paper preparation, she was inspired by the idea that she submitted to the Academy on March 2, 1774. In a letter from 1783, she explained that she often experimented while working. Men from the Academy expressed deep skepticism regarding female inventions. After twelve years of testing, the Ministry of War approved it, recognized the inventor, and gave her an award in 1786. Her invention was used for a long time in the Swedish army.
