Johann Georg Christian Lehmann was the son of pastor Johann Gottlieb Lehmann († 1807) and his wife Maria Elisabeth, née Zornickel. The German-Danish lawyer and naturalist Martin Christian Gottlieb Lehmann was his brother.

Lehmann studied medicine in Copenhagen and Göttingen and earned a doctorate in medicine in 1813 and a doctorate in philosophy at the University of Jena in 1814 . In February 1818 he was elected professor for physics and natural history at the Academic Gymnasium Hamburg . In September of the same year he became the first librarian at the city ​​library and successor to Christoph Daniel Ebeling . On August 26, 1818 Lehmann became a member of the Kaiserl. Society of Naturalists (Leopoldina), 1843, he was named "Helianthus III." The adjunct chosen society. In 1821 he founded the Botanical Garden in Hamburg , which he also became director. In 1822 he was accepted as a corresponding member of the Russian Academy of Sciences in Saint Petersburg . Lehmann was a member of numerous societies, including the Society of Friends of Natural Sciences in Berlin , the Society of Natural Sciences in Halle, the Society for the Entire Mineralogy of Jena, and others. v. a.

Lehmann was the founder of the botanical garden in Hamburg. In his opinion, due to its location and connections to distant areas, Hamburg was suitable for founding an institute in which plants from these countries, whose knowledge is of great importance, could be scientifically examined. In 1819 Lehmann informed the Senate of his ideas. The Senate showed interest and was ready to provide a site, but was not ready to install the institute planned by Lehmann as part of the academic high school. Lehmann had to undertake to regard the botanical garden as his private affair, to admit visitors, to carry out the administration and to not run a restaurant on the site. Lehmann planted the first tree in November 1821. A few days later, Johann Heinrich Ohlendorff started working as a gardener. Lehmann succeeded in building a training institute for young people. In March 1825 the first had finished their training after three years of apprenticeship. In the following years greenhouses were partly built with steam heating. Lehmann received considerable support through donations from the citizens of Hamburg. In 1833, according to Lehmann's request, the botanical garden and the attached institute were left to the City of Hamburg as a public matter. The positive response to the meeting of the Society of German Natural Scientists and Doctors in Hamburg in 1830 is said to have contributed to the recognition .

In the period from 1828 to 1834, Johann Georg Christian Lehmann and John Richmond Booth, as owners of the commercial nursery and tree nursery James Booth & Sons, carried out the "rose dispute" known from numerous publications. Christian Gottfried Daniel Nees von Esenbeck took Lehmann's side in his publication Der Rosenstreit in the magazine Flora or [general] botanical newspaper . John Booth's brother Georg published his view of the situation in Victory of the Rose "Queen of Denmark" by exposing the attacks by Professor JGC Lehmann . This dispute was about Lehmann's finding that a rose with the name “la belle courtisanne” would be referred to in some catalogs by commercial gardeners as the “Queen of Denmark”. Booth, however, was of the opinion that it was a rose drawn and named by him. The dispute ended with a published statement by Lehmann in March 1834, in which he stated that his statement was a mistake.

Johann Georg Christian Lehmann was married to Dorothea Baltzer (* 1801) since 1824. From this marriage comes, among others, Johannes Christian Eugen Lehmann , Senator and temporarily First Mayor of Hamburg.

Lehmann owned an extensive herbarium. After his death it was offered for sale by the botanist Friedrich Wilhelm Klatt .
