In 1997 I created the Ultimate Stabat Mater website for Hans with the program FrontPage. At that time he had around 40 Stabat Mater CDs. His notes on the composer, the music, the texts and translations and the different versions all came online. After this he managed the site by adding new composers and translations regularly. At the time of his death in 2005 he had 211 Stabat Maters. After his death I continued collecting the information and managing the site. I wish to thank the Dutch Stabat Mater Foundation which gave me the financial support in 2014 to renew this site!
