Gerrit Thomas Rietveld (b. 1888) was a Dutch furniture designer and architect, born in Utrecht, Netherlands. He is especially known for his pioneering work in the field of modern design and is considered one of the most important designers of the 20th century. One of Rietveld's most famous works is the Red and Blue Chair, which he designed in 1917. The chair has a simple geometric design that reflects Rietveld's interest in abstraction and simplicity. The Red and Blue chair is still one of the masterpieces of modernist design and is exhibited in many museums around the world. In addition to furniture, Rietveld also designed several important buildings, including his own home, the Rietveld Schröder House in Utrecht.

Rietveld started his career as a carpenter but soon became interested in furniture design and architecture. He was a member of the De Stijl art movement, which sought to create a new, abstract art form that would reflect the modern world, and his work was heavily influenced by the main principles of this movement: simplicity, purity, and functionality.

Throughout his career, Rietveld remained committed to the principles of modernism as well as the use of new materials and technologies. His work continues to be influential today and is considered a cornerstone of modern design.
