Laurent de Chazelles was born in Metz, France, on July 28, 1724. He was the son of a tax collector and became the lawyer for the Parliament of Metz, taking over his brother's tenure (Louis de Chazelles; 1722-1751).

He has a castle built on his land at Lorry-devant-le-Pont, near Metz, which included magnificent greenhouses that he filled with exotic plants. His Lorry greenhouses' were paid tribute in a poem, titled Templum Metensibus sacrum by Bernardin Pierron.
