Bryggman was the only architect with whom Aalto cooperated as an equal. With an increasing quantity of work in the Finnish capital, the Aaltos' office moved again in 1933 to Helsinki. The Aaltos designed and built a joint house-office (1935–36) for themselves in Munkkiniemi, Helsinki, but later (1954–56) had a purpose-built office erected in the same neighbourhood – now the former is a "home museum" and the latter the premises of the Alvar Aalto Academy. In 1926, the young Aaltos designed and had built for themselves a summer cottage in Alajärvi, Villa Flora. Aino and Alvar had two children, a daughter, Johanna "Hanni" (married surname Alanen; born 1925), and a son, Hamilkar Aalto (born 1928). Aino Aalto died of cancer in 1949. In 1952, Aalto married architect Elissa Mäkiniemi (died 1994). In 1952, he designed and built a summer cottage, the so-called Experimental House, for himself and his second wife, now Elissa Aalto, in Muuratsalo in Central Finland. Alvar Aalto died on 11 May 1976, in Helsinki, and is buried in the Hietaniemi cemetery in Helsinki. Elissa Aalto became the director of the practice, running the office from 1976−1994. In 1978, the Museum of Finnish Architecture in Helsinki arranged a major exhibition of Aalto's works. Architecture career Early career: classicism Although he is sometimes regarded as among the first and most influential architects of Nordic modernism, closer examination reveals that Aalto (while a pioneer in Finland) closely followed and had personal contacts with other pioneers in Sweden, in particular Gunnar Asplund and Sven Markelius. What they and many others of that generation in the Nordic countries shared was a classical education and an approach to classical architecture that historians now call Nordic Classicism. It was a style that had been a reaction to the previous dominant style of National Romanticism before moving, in the late 1920s, towards Modernism. Upon returning to Jyväskylä in 1923 to establish his own architect's office, Aalto designed several single-family homes designed in the style of Nordic Classicism. For example, the manor-like house for his mother's cousin Terho Manner in Töysa (1923), a summer villa for the Jyväskylä chief constable (also from 1923) and the Alatalo farmhouse in Tarvaala (1924). During this period he completed his first public buildings, the Jyväskylä Workers' Club in 1925, the Jyväskylä Defence Corps Building in 1926 and the Seinäjoki Civil Guard House building in 1924–29. He entered several architectural competitions
