You mean Andy Kay? Yes, he is still around.

Folks -- There is a cooler and most interesting way to approach all this. Much of the seminal work was done around the late 70s in PARC Smalltalk by Ira Goldstein and Danny Bobrow -- it was called PIE: Personal Information Environment -- and they have been written up as PARC Blue Books (as noted by Mike Klein previously to the Squeak list) ; *and* they can sometimes be obtained from PARC. The basic idea is to have an object made up of multiple perspectives e.g. a given object could have the perspectives of being an employer, an employee, a father, a son, etc., *and* the perspective of being an object. The internal representational strategy they used was to let a logical object be made of as many Smalltalk instances as were needed, especially if the perspectives were disjoint enough to give fits to simple-minded mulitple inheritance schemes. I have been a big fan of this general approach since Goldstein got it running. There are also a wealth of other terrific ideas in their papers. Cheers, Alan
