Lorenz Florenz Friedrich von Crell (21 January 1744 – 7 June 1816) was a German chemist.

[1] Lorenz Crell was born in the Duchy of Brunswick's university town of Helmstedt as the son of medical professor Johann Friedrich Crell and grandchild of medical professor Lorenz Heister, who achieved renown in surgery and botany.

At the age of fourteen, he entered the University of Helmstedt where, after nearly a decade of taking courses offered by the philosophical and medical faculties, he took his M.D.

In 1771, soon after his return to the Duchy of Brunswick, Crell secured an appointment in Braunschweig's Collegium Carolinum as professor of metallurgy.

In 1778 Crell published the first issue of the Chemische Journal für die Freunde der Naturlehre, Arzneygelahrtheit, Haushaltungskunst und Manufacturen.
