Peter Landrock grew up in Denmark and obtained his PhD in mathematics in 1974 from the University of Chicago. He began working on data security in 1984 whilst at Aarhus University, and built up one of the leading data security research teams within Europe. He founded Cryptomathic in 1986, one of the first companies to commercialise cryptographic algorithms, but it was his participation in the 1996 Isaac Newton Institute programme on Cryptology and Coding Theory that inspired him to leave academia and focus on the company. Always emphasising the importance of the underpinning mathematics, Cryptomathic went from strength to strength and is now one of the world’s leading providers of security solutions to businesses across a wide range of industry sectors, including banking, government, technology, cloud and mobile. ' Attending the Newton Institute workshop, a new world opened in front of my eyes... The following year I was still so inspired from my time at the Newton Institute that I decided to quit my position at Aarhus University and concentrate on my company'.
