(MILWAUKEE, WI – May 14, 2026) Kahler Slater announces with deep respect and gratitude the passing of David Kahler, FAIA, a visionary architect, mentor and leader whose influence continues to shape the firm and the design profession.
David Kahler joined the firm in 1965 and, from the outset, championed architecture as an act of service to communities. From 1974 to 2002, he led the firm alongside Thomas “Mac” Slater, helping to shape Kahler Slater into a nationally respected practice defined by design excellence, integrity and collaboration.
As an architect, Kahler set a standard that balanced rigor with imagination. He emphasized clarity of thought, respect for context and honesty in materials, while encouraging bold ideas and thoughtful questioning. Among his earliest and most influential works was the Golda Meir Library at the University of Wisconsin–Milwaukee, completed in 1967, an enduring campus landmark that continues to serve generations of students and scholars.
Kahler also led the 11‑year, phased restoration of the Wisconsin State Capitol from 1991 to 2002, a complex and highly visible effort that required technical mastery and careful stewardship of one of the state’s most important civic landmarks.
His longstanding relationship with the Milwaukee Art Museum produced two significant contributions: the Bradley Wing addition, completed in 1975 and nationally recognized, and later the Quadracci Pavilion, completed in 2001 in collaboration with Santiago Calatrava. The Pavilion transformed the museum into an international architectural icon and became a defining symbol of both the city of Milwaukee and the state of Wisconsin.
Beyond his built work, Kahler’s legacy is deeply rooted in mentorship and leadership. He invested in people throughout his career, empowering generations of architects to grow as professionals guided by principle, curiosity and collaboration.
“David’s vision and commitment to design excellence and community service set a course that continues to guide the firm,” said Al Krueger, AIA, CEO of Kahler Slater. “His legacy lives on in the work we carry forward.”
Kahler was recognized as a Fellow of the American Institute of Architects, reflecting the high regard in which he was held by the profession. Colleagues remember him for his humility, humor, and belief in the strength of teams working together in service of clients and communities.
While the firm mourns his passing, they celebrate his legacy found in the buildings he helped shape, the culture he helped build, and the people he inspired. His principles remain embedded in the firm’s work and values.
