Albert Kahn (March 21, 1869 – December 8, 1942) was an American architect noted for his collaborations with his brother Julius Kahn in designing industrial plant complexes such as the Ford River Rouge automobile complex. Based in Detroit, he also designed skyscrapers, office buildings, and mansions in the city and suburbs, as well as many buildings at University of Michigan in Ann Arbor. Kahn has been called the "architect of Detroit" as the designer of nearly 900 buildings in the city.

Kahn led an organization of hundreds of architect associates, and in 1937, designed 19% of all architect-designed industrial factories in the United States. Under a unique contract in 1929, he established a design and training office in Moscow, sending twenty-five staff there to train Soviet architects and engineers, and to design hundreds of industrial buildings under their first five-year plan. They trained more than 4,000 architects and engineers using Kahn's concepts. In 1943, the Franklin Institute posthumously awarded Kahn the Frank P. Brown Medal.

Kahn was born on March 21, 1869, to a Jewish family in Rhaunen, in the Kingdom of Prussia, today in Germany. He received his early education in the school of Luxembourg. At age twelve in 1881, Kahn immigrated with his family to Detroit, Michigan. His father Joseph was trained as a rabbi; his mother Rosalie had a talent for the visual arts and music. Kahn had four brothers, including Moritz, who became an engineer, and Julius Kahn, an engineer and inventor, who later collaborated with him in his architectural firm. They also had two sisters, one of whom, Mollie Kahn Fuchs, later worked closely with Julius to create a type of reinforced concrete that would later be patented.

When the family immigrated to America, Kahn quickly learned English and went to Detroit public schools. In 1883, he got a job at the architectural business of Mason and Rice where he got his initial architectural training, working primarily on residences and bank buildings.

In 1891, at age 22, Kahn won a Rotch Traveling Fellowship to study in Europe, where he toured Germany, France, Italy, and Belgium with fellow student Henry Bacon, who later designed the Lincoln Memorial in Washington, D.C.

Kahn married Ernestine Krolik in 1896, and they had four children. Ernestine would later briefly serve as a vice president in her husband's business, and often helped him with color and fabric selection in designs.

Kahn left Mason and Rice in 1895, entering into a partnership with Alexander B. Trowbridge and George W. Nettleton known as Nettleton, Kahn & Trowbridge. In 1902, Kahn formed a partnership with his brother Julius, a civil engineer. Later that year, Julius developed a novel and scientific method of reinforcing concrete with steel, making reinforced concrete construction practical and economical. After receiving a patent on the "Kahn System" of construction in 1903, Julius left Kahn's firm and established the Trussed Concrete Steel Company, or Truscon, to market the product. Reinforced concrete allowed for much larger open spaces within factory interiors not obtainable with conventional wood construction and at a lower cost than steel frame construction. Concrete had other beneficial characteristics, such as far better protection from fire and greater load-bearing capacity. By 1905, hundreds of buildings within the United States were being constructed using the Kahn System, including the first reinforced concrete automobile plant, completed for the Cadillac Motor Car Company at 450 Amsterdam Street in TechTown, Detroit. Julius Kahn collaborated with his brother on the design of many industrial projects throughout the US constructed with reinforced concrete, particularly automobile factories, with the result that Kahn became widely known for his expertise in the construction of concrete industrial structures.

Kahn was also responsible for designing many of the buildings and houses built under the direction of the Hiram Walker family in Walkerville, Ontario, including Willistead Manor. Kahn's interest in historically styled buildings is also seen in his houses in Detroit's Indian Village, the Cranbrook House, the Edsel & Eleanor Ford House, and The Dearborn Inn, the world's first airport hotel. Kahn's firm designed the Art Deco Fisher Building in Detroit's New Center area, a 28-story designated landmark. In 1929, the building was awarded a silver medal by the Architectural League of New York in the category of the year's most beautiful commercial building. From 1917 to 1929, Kahn's firm also designed the corporate headquarters for all three of the major Detroit daily newspapers and the General Motors building, at the time of its completion in 1922, the second-largest office building in the world. His work was part of the architecture event in the art competition at the 1928 Summer Olympics.
