Gerry Turley is an illustrator and printmaker. He was born and raised in Glasgow where he studied Illustration at the Glasgow School of Art, and then Natural History Illustration at the Royal College of Art.

His illustrations are made by building layers of print and drawing to make distinctive images. He is known for his sensitive depiction of animals, often drawn on location - one of the most memorable drawing trips was to the Swiss Alps in an area where a bear had been spotted shortly before - exciting and a bit unnerving!
