Buehler was founded 1936 by Adolph I. Buehler, a Swiss immigrant who saw a need for metallographic sample preparation equipment and optical inspection instruments for the steel and automotive industries in the USA. Starting with a product line consisting of optical inspection instruments, a mounting press and a polisher, today Buehler is now well established as the world’s leading supplier of materials preparation and analysis instruments, equipment, consumable supplies and application solutions. Buehler merged with Wilson Hardness in 2011 to offer a complete line of material preparation and analysis equipment.
