Selwyn Philip Haas and Raymond Colin Haas are among the founding members of the open public foundation Liepājas ebreju mantojums (Liepāja Jewish Heritage Foundation) since 2004.

Their paternal ancestors came from Liepāja and Pavilosta. In 1998 Selwyn and Raymond visited Latvia to research into their father’s, Ivor’s (Idel), youth in Liepāja. Since then both brothers have become vital members of the Liepāja’s Jewish Community. As the founding members, Selwyn and Raymond Haas support various projects and activities directed to research and preserve Jewish heritage of Liepāja as well as to ensure development of the new-generation of the Jewish Community in Liepāja.
