Pat qualified as a Leather Chemist at Leeds University, where he met his future wife, Margot. He started his career in the early 1950s, working as a leather technician for the Stimpson Perkins Group in Northampton.

He later joined the William Clarke Currying Company based in Margate, Kent, to develop new leathers for the domestic and international footwear market. In the early 1970’s Pat became Managing Director of the Midland Leather Company in Rochdale, supplying major shoe companies such as Startrite and Clarks shoes with chrome tanned upper leathers.

He was elected President of the British Leather Federation (now known as the UK Leather Federation – UKLF) in 1978–79 and always considered this to be a great honour. Midland Leather was then acquired by Pittards, and later absorbed by Miers of Leeds.  Pat Patrick became Managing Director of Miers in 1981. After his retirement in 1993, he was often recalled as a Consultant to the Pittards Group.
