He studied in the high school of Neuchâtel and then in the Technical School of Stuttgart and in the university of Munich.[1] After graduating in mathematics in Munich, he began to teach in a private school. Soon, in 1880, he was appointed to the chair of mathematics in the Lycée Cantonal of Porrentruy, where he remained till 1908 when his ill health forced him to retire.[2]

In mathematical world he is known by a theorem, the Droz-Farny line theorem, stated by him in 1899, without proof,[3] in an answer to question 14111 in the journal The Educational Times.
