I appreciated the chance to work with Margaret.  She was retired but worked with me as a "temp".  Her work was at the top of the line and she was a wonderful and highly skilled person.  I felt lucky every day that she stayed on to work with me.  
Condolences to her family that I know will miss her.  As I go to sleep tonight, it is with the feeling that Margaret left the world a better place--something we should all aspire to acoomplish.
