After his early death his widow maintained the business, and in 1864 the mechanical engineer Ernst Leitz entered the company. Just five years later, Leitz took control of the firm and changed its name for Ernst Leitz Wetzlar. Leitz led the company to success after introducing improvements such as serial production, raising sales volume rapidly after 1871. Leitz microscopes included technical improvements that increased their quality; by the late 19th century the company already had a worldwide reputation. Ernst Leitz died in 1920 and the leadership of the firm passed to his son. As well as for their microscopes and optic material, Leitz became hugely famous for their famous Leica cameras (abbreviation of Leitz Camera).
