David Quay is one of the principals of The Foundry type design partnership. He is a graphic designer, type designer, typographer and teacher, originally from London now resident in The Netherlands. He has also designed fonts for Letraset, ITC, and Berthold AG.

David studied graphic communication at Ravensbourne College of Art & Design from 1963–67. For the next seven years he worked in various leading London design companies as a packaging and graphic designer. From 1975 he worked as a freelance designer specializing in lettering and logotypes, until forming Quay & Gray with Paul Gray, in 1983. He started his own company David Quay Design in 1987 to concentrate on graphic and typographic design. He also began to design his first text typefaces subsequently released by the International Typeface Corporation (ITC), New York and H Berthold AG, Germany.

Since the late 1980s he has worked in partnership with Freda Sack on a broad range of type projects. The natural progression for their collective skills and experience was setting up an independent type foundry, and in 1989 they co-founded The Foundry, to design, manufacture and licence their exclusive typefaces. As a partnership their commissions have included bespoke typefaces, marks and logotypes – a directory typeface to be readable at very small sizes for Yellow Pages (awarded a D&AD Silver); corporate fonts for BG plc (British Gas) and NatWest bank, as well as signage typefaces for the UK railway infrastructure and the Lisbon Metro system, Portugal.

David lectures internationally in typography and type design. He has had a long association with the London College of Printing (now LCC) and was a visiting lecturer at the Danmarks Designskole Copenhagen and the Hochschule für Gestaltung Offenbach. For three years he was professor of typography and book design at the Fachhochschule Mainz. In 2000 this prompted a move from London to Wiesbaden. Based in Amsterdam from 2001, he taught typography and design at Akademie voor Kunst en Vormgevin St Joost /Avans Hogeschool Breda. He continued to work closely with Freda Sack and Foundry Types in London to expand The Foundry typeface library.

David was one of the founder members of Letter Exchange, and its chairman for many years. He was elected a Fellow of the International Society of Typographic Designers (ISTD) in 1992 and was joint chair of the society with Freda Sack from 1994–9. During this period they ran a popular lecture series inviting leading international speakers to London. The Dutch lectures led to David's connection with Amsterdam, and The Foundry's collaboration with Wim Crouwel on the Architype Crouwel Collection and Foundry Gridnik

Currently David lives in The Netherlands working as a type and graphic designer and creating new typefaces for The Foundry.
