Toyo Ito
After apprenticing with Toyo Ito, Sejima established Kazuyo Sejima &amp; Associates in 1987. One of her first hires was Ryue Nishizawa, a student who had worked with Sejima at Toyo Ito and Associates. After working for Sejima for several years, Sejima asked him to form a partnership. In 1995, the two founded the Tokyo-based firm SANAA (Sejima and Nishizawa and Associates). In 2010, Sejima was appointed director of architecture sector for the Venice Biennale, which she curated for the 12th Annual International Architecture Exhibition. She was the first woman ever selected for this position. In 2010, she was awarded the Pritzker Prize, together with Ryue Nishizawa.
