Ludwig Mies van der Rohe ( MEESS; German: [mi:s]; born Maria Ludwig Michael Mies; March 27, 1886 - August 17, 1969) was a German-American architect. He is commonly referred to and was addressed as Mies, his surname.

Between 1946 and 1951, Mies van der Rohe designed and built the Farnsworth House, a weekend retreat outside Chicago for an independent professional woman, Dr. Edith Farnsworth. Here, Mies explored the relationship between people, shelter, and nature. The glass pavilion is raised six feet above a floodplain next to the Fox River, surrounded by forest and rural prairies.  The highly crafted pristine white structural frame and all-glass walls define a simple rectilinear interior space, allowing nature and light to envelop the interior space. A wood-panelled fireplace (also housing mechanical equipment, kitchen, and toilets) is positioned within the open space to suggest living, dining and sleeping spaces without using walls. No partitions touch the surrounding all-glass enclosure. Without solid exterior walls, full-height draperies on a perimeter track allow freedom to provide full or partial privacy when and where desired. The house has been described as sublime, a temple hovering between heaven and earth, a poem, a work of art.  The Farnsworth House and its 60-acre (240,000 m2) wooded site was purchased at auction for US$7.5 million by preservation groups in 2004 and is now owned and operated by the National Trust for Historic Preservation as a public museum. The building influenced the creation of hundreds of modernist glass houses, most notably the Glass House by Philip Johnson, located near New York City and also now owned by the National Trust.  The house is an embodiment of Mies' mature vision of modern architecture for the new technological age: a single unencumbered space within a minimal "skin and bones" framework, a clearly understandable arrangement of architectural parts. His ideas are stated with clarity and simplicity, using materials that are configured to express their own individual character.
