His parents were the lawyer and politician Jean-Charles Sarasin (1806–1867) and Louise Marie Emilie, b. Rigaud.

From 1875, Sarasin worked with Jacques-Louis Soret on a study of circular polarization in quartz. Between 1890 and 1892 he researched radio waves with Augustes son, Lucien de la Rive . You were in correspondence with Henri Poincaré about the resonance phenomena . In 1869 he became editor and after Sorets death 1890–1915 editor-in-chief of the Archives des sciences physiques et naturelles in Geneva. 1911-16 he was also the central president of the Swiss Society for Natural Sciences. In 1885 the University of Basel and in 1909 the University of Geneva awarded him an honorary doctorate.

Sarasin was also politically active, for 25 years as a member of the cantonal parliament of Geneva and as a long-term mayor (1871 to 1916) of his municipality of Le Grand-Saconnex. There the street was named after him, which leads past Parc Sarasin and the Villa Sarasin , built in 1833 .
