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.

Mies was born March 27, 1886 in Aachen, Germany. He worked in his father's stone carving shop and at several local design firms before he moved to Berlin, where he joined the office of interior designer Bruno Paul. He began his architectural career as an apprentice at the studio of Peter Behrens from 1908 to 1912, where he was exposed to the current design theories and to progressive German culture, working alongside Le Corbusier and Walter Gropius, who was later also involved in the development of the Bauhaus. Mies served as construction manager of the Embassy of the German Empire in Saint Petersburg under Behrens.  His talent was quickly recognized and he soon began independent commissions, despite his lack of a formal college-level education. A physically imposing, deliberative, and reticent man, Ludwig Mies renamed himself as part of his rapid transformation from a tradesman's son to an architect working with Berlin's cultural elite, adding "van der" and his mother's surname "Rohe", using the Dutch "van der", because the German form "von" was a nobiliary particle legally restricted to those of genuine aristocratic lineage.  He began his independent professional career designing upper-class homes, joining the movement seeking a return to the purity of early 19th-century Germanic domestic styles. He admired the broad proportions, regularity of rhythmic elements, attention to the relationship of the man-made to nature, and compositions using simple cubic forms of the early nineteenth century Prussian Neo-Classical architect Karl Friedrich Schinkel. He rejected the eclectic and cluttered classical styles so common at the turn of the 20th century as irrelevant to the modern times.
