We are honored to showcase the estate of Donna Ruedy-Hermann
Born November 5th, 1936, Donna Gail Ruedy was a third generation Californian; enigmatic and uniquely glamorous. She earned her PHD in Art, and retired Emeritus. In the early 1960s, Donna met John Hermann, a professional athlete turned recruiter/coach and fellow educator. They spent decades traveling the world, building their extensive collection. Donna passed away in May of 2020, leaving behind so much mystery and treasure. We are humbled that our dear friend Sammy invited us into the world of Donna and John. Isadoras is honored to have been chosen to pass Donna's lifetime of collecting to our valued clientele. This experience has been heartwarming and the memory of a lifetime. At her request, a portion of the proceeds from the sale of her jewelry will be donated to Pasadena Humane Society.
