Migrating Modernism. The Architecture of Harry Seidler presents the extraordinary personal history and built work of Austrian-born Australian architect Harry Seidler (Vienna, 1923 – Sydney, 2006). One of two exhibitions inaugurating SMAC Venice, the show was curated by Ann Stephen and Paolo Stracchi from the University of Sydney's Chau Chak Wing Museum (CCWM), with Nikolaus Hirsch as curatorial advisor, and organised in partnership with CCWM. Opening on 9 May 2025 to coincide with the 19th Architecture Biennale, the exhibition ran until 20 July 2025.

Spanning drawings, models, letters, photographs, and personal documents, the retrospective considers both Seidler's individual projects and his collaborations with artists and architects including Josef Albers, Alexander Calder, Helen Frankenthaler, Frank Stella, Sol LeWitt, and Italian structural engineer Pier Luigi Nervi. Seidler's life — from his escape from Nazi-ruled Vienna as a teenager, through internment in England and Canada as an enemy alien, to his studies under Gropius, Breuer, and Niemeyer, and his eventual arrival in Sydney in 1948 — is understood as both a personal journey and a narrative of modernism's global migration.
