Herzog & de Meuron Architekten is a Swiss architecture firm, founded and headquartered in Basel, Switzerland in 1978. The careers of founders and senior partners Jacques Herzog (born April 19th, 1950), and Pierre de Meuron (born May 8th, 1950), closely paralleled one another, with both attending the Swiss Federal Institute of Technology (ETH) in Zurich. They are perhaps best known for their conversion of the giant Bankside Power Station in London to the new home of the Tate Museum of Modern Art. Jacques Herzog and Pierre de Meuron have been visiting professors at the Harvard University Graduate School of Design since 1994 and professors at ETH Zurich since 1999.

In 2001, Herzog & de Meuron were awarded the Pritzker Prize, the highest of honours in architecture. Jury chairman J. Carter Brown, commented, "One is hard put to think of any architects in history that have addressed the integument of architecture with greater imagination and virtuosity." This in reference to HdeM's innovative use of exterior materials and treatments, such as silkscreened glass. Architecture critic and Pritzker juror Ada Louise Huxtable summarized HdeM's approach concisely: "They refine the traditions of modernism to elemental simplicity, while transforming materials and surfaces through the exploration of new treatments and techniques."

Herzog & de Meuron's early works were reductivist pieces of modernity that registered on the same level as the minimalist art of Donald Judd. However, their recent work at Prada Tokyo, the Barcelona Forum Building and the Beijing National Stadium for the 2008 Olympic Games, suggest a changing attitude.

Their commitment of articulation through materiality is a common thread through all their projects. Their formal gestures have generally progressed from the purist simplicity of rectangular forms to more complex and dynamic geometries. The architects often cite Joseph Beuys as an enduring artistic inspiration and collaborate with different artists on each architectural project. Their success can be attributed to their skills in revealing unfamiliar or unknown relationships by utilizing innovative materials.
