From microscopic to astronomic, the legacy of Carl Zeiss.
IN 1846, CARL ZEISS established a workshop to make lenses for microscopes, cameras, binoculars, and astronomical observatories. He was a master craftsman and was intolerant of any flaw, destroying microscopes with only minor inaccuracies. His relentless pursuit of perfection brought him into contact with a brilliant physicist, Ernst Abbe. Zeiss combined Abbe's new optical laws with his own technical skills; together, they created a colossus. Their company came to be known not only for exquisite technical standards but also for labor relations that were and remain progressive. The development of microneurosurgery was aided by the active participation of Carl Zeiss, Inc. The history of this company provides a lesson in the power of entrepreneurship and the benefits to humanity that can accrue from a fruitful partnership between medical science and industry.
