Melinda Mathias Walsh

Granddaughter of Oscar Hammerstein II


I was nine years old when my grandfather died.  My memories of him are that of a small child and much like any other child’s, nothing terribly unique.  My lasting impression of him has been shaped by the stories and personal letters passed down to me by my mother and other relatives.  When I think of my grandfather, I think of a life lived with integrity and humanity, a model for what it is to be a good citizen of the world.  He once said “When a writer writes anything about anything at all, he gives himself away.”   I think these characteristics shine in all of his work.  He believed that the good in humanity would prevail, a belief we cling to now while seeking comfort and hope .
