HISTORY: Busch microscopes in general are not rare as many were produced. They were exported to the USA in the early 20th century and were sold by retailers like P. Aloe. The stands are of reasonably good quality construction. Like the other German microscope makers, they made several different sizes of stand and both a larger and a smaller pocket stand are also part of this collection. Their smaller pocket microscope was very popular and an example of it is also in this collection. Emil Busch took over an optics firm from his uncle August Duncker in about 1845 and built a considerable enterprise that grew even after his death in 1888. The firm prospered making photographic equipment, binoculars, etc until WWII. Remnants of the company were absorbed by optical companies in East Germany after WWII. Zeiss may have supplied their optical glass.
