Katherine Loker was a woman of seemingly infinite vision, energy, and drive, with a loving heart singularly focused on leaving the world better than she found it through a near-lifetime of her and her beloved late husband Donald’s discerning philanthropy. As a devoted friend of President and Mrs. Nixon, she participated in countless ways in the protection and extension of his legacy of peace, including by playing the lead role in the establishment of the Katherine B. Loker Center and the White House East Room at the Nixon Library. If her schedule permitted, she never missed an event at the Library. We will miss her laughter, love of politics, and sharp insights about all aspects of our work. A great runner at her beloved USC, she ran a great race for all her years. She was the greatest friend any institution, and any person, could have.
