Professor Dr Ursula Klein

Ursula Klein is known for her work on “paper tools” and modes representations in the history of the laboratory sciences. She is the first historian of science who showed that chemical formulae, introduced By Jöns Jacob Berzelius in 1813/14, had path-breaking heuristic functions in the process of the formation of modern organic chemistry (carbon chemistry) from the late 1820s until the early 1840s.
More recently, she has been working on the history of “applied sciences” or “technosciences.” The systematic and stable interconnection of scientific and technological research into an “applied science,” or “technoscience,” is usually considered to be the outcome of the twentieth century. By contrast, Klein’s new research project studies stable intersections of scientific and technological practices, along with scientific-technological experts, in a much earlier period, namely from the late seventeenth until the early nineteenth century. Central to her research is the historical analysis of experiments and of the material culture of early modern laboratories established at apothecary’s shops, the mining and metallurgical business, porcelain manufactories and arsenals as well as at universities and scientific academies; a specific focus is on eighteenth-century Prussia.
