This magazine was published by Prof. Hans Georg Näder in honour of Dr. Max Näder.Dr. Max Näder (24.6.1915-24.7.2009) is considered a pioneer and driver of technical orthopaedics. Born in Thuringia, Germany, he founded the Orthopädische Industrie KG in Duderstadt in southern Lower Saxony in 1947, at the same time that the main factory of his father-in-law Otto Bock was on the verge of being expropriated in Königsee, Thuringia. This founding was followed by others: Otto Bock Kunststoff GmbH in 1953, and the first foreign branch in Minneapolis (United States) in 1958, marking the start of the company's global expansion. In 1990, Max Näder handed over management of the company to his son Prof. Hans Georg Näder, under whose leadership the company has grown to become a global medical technology business. Prof. Näder is using the occasion of the centenary of the birth of his father to document Max Näder's entrepreneurial and private life.
