Adolf Dassler was a German entrepreneur who founded the famous sportswear company Adidas. He started the business in his mother's laundry room in the 1920s, making shoes using spare materials and with help from his brother. As an entrepreneur, Dassler worked hard to produce all the shoes himself, took risks by providing shoes to athletes without knowing the outcome, and was creative in developing ideas that made Adidas a top sports brand through effective communication with athletes.
