[Smt-talk] email address or other contact information for the estate of Ernst Oster

[Anders Tobiason]

Hi All,
I am having trouble finding contact information for the estate of Ernst Oster. I need to reproduce a figure from Free Composition (the longman edition) in my dissertation and it seems that they hold the copyright. 
Both public and private replies welcome.
Thanks for everyone's help.
