In their publications during the 1820s, Jakob Steiner and Julius Plücker frequently derived the same results while claiming different methods. This paper focuses on two such results in order to compare their approaches to constructing figures, calculating with symbols, and representing geometric magnitudes. Underlying the repetitive display of similar problems and theorems, Steiner and Plücker redefined synthetic and analytic methods in distinctly personal practices.Communicated by : Jeremy Gray.Research for this article was made possible through the generous assistance of the École Polytechnique archives in Palaiseau, the Hochschularchiv of the Eidgenössische Technische Hochschule in Zürich, and the National Research Council of Canada archives in Ottawa.
