He was born on 26 February 1770 (according to other sources - in 1768) in the family of Anna Maria Savitsky. He was adopted by Karl Schleicher after the death of his father. In 1797 he married Julie Ricou, daughter of the physician Jean-David Ricou. Schleicher settled in Bévieux sur Bex around 1800, where he worked in a pharmacy. He was also the owner of a company selling plants and herbarium specimens. He created the first botanical garden in the canton of Vaud in the city of Bevieux and is considered to be the inventor of the commercial catalogs of plants, of which he published the first copy of 76 pages in 1800. It was followed by other editions, in 1807, 1815, and 1821. Schleicher was the first scientist to use mercury chloride to store herbarium specimens. Johann Christoph died in Bex on 27 August 1834. Currently, the bulk of Schleicher's herbarium specimens are kept in the Conservatory and Botanical Garden of the City of Geneva and the Lausanne Museum and Botanical Garden (LAU). Selected works
