1849-1910
Carl Kellner founded the Optical Institute in Wetzlar in 1849 to make optical instruments. Ernst Leitz joined in 1864, became a partner in 1865, and took sole control after Friedrich Belthle's death in 1869, continuing the firm under his own name. Serial production and international sales made microscopes the business's foundation long before it manufactured the small-format camera now associated with Leica.
