Rare works by Jean Welz from the collection of his son, Strauss & Co’s founding director Stephan Welz, poised to go under the hammer 

19 May 2026

Strauss & Co is pleased to announce details of a single-owner auction of modern and contemporary art, Cape furniture, ceramics and a library of books assembled by the legendary South African auctioneer Stephan Welz and his wife Carmen Welz. The sale Deep Roots: Selected Works from Stephan and Carmen Welz (Wednesday, 27 May 2026) includes a large consignment of paintings, drawings and prints by Welz’s father, the acclaimed modernist painter Jean Welz.

“It is a bittersweet sale for us,” says Alastair Meredith, Director and Head of Sale, Strauss & Co. “In 2008, Stephan Welz came out of retirement to establish Strauss & Co with respected business leaders Elisabeth Bradley and Dr. Conrad Strauss. Drawing on deep reservoirs of experience, he helped transform the start-up business into the largest auction house in Africa and a global leader in the secondary market for South African art. It is an immense privilege to be handling the objects and artworks he lived with every day in his home in Parkview, Johannesburg.”

Deep Roots: Selected Works from Stephan and Carmen Welz will be presented as a two-part sale, with the modern and contemporary art, Cape furniture and diverse ceramics presented in a standalone live-virtual auction. A separate online-only sale of Welz’s library of artist monographs and reference books on silverware, which informed his landmark book Cape Silver & Silversmiths (1976), will open on Strauss & Co’s website on 30 April 2026 and close 28 May 2026 from 2pm.

The art consignment includes paintings by Irma Stern, Frans Oerder and Jean Welz. Deep Roots: Selected Works from Stephan and Carmen Welz includes 58 works by Jean Welz, an Austrian-born architect who in later years excelled as a painter after settling in the Cape. They include abstract and figurative paintings, drawings and prints. There are also works by Karel Nel, William Timlin and Adolph Jentsch on offer.

The furniture consignment reflects Welz’s appreciation for period furnishings and includes a 14-seater dining-room table, military and navel chests, Cape chairs, a writing bureau and other pieces. The ceramics range from blue-and-white porcelain and Victorian figurines to pieces by local makers Kalahari and Linnware. Estimates will be attractive to a broad range of buyers.

Works from Deep Roots: Selected Works from Stephan and Carmen Welz is on display in Strauss & Co’s gallery in Houghton. The intimate room displays, curated by Wilhelm van Rensburg, Chief Curator, Strauss & Co, offers an interpretation of the domestic origin and milieu of the works being offered.
