Caplin’s passion for the arts can be traced back to his college years when he was president of the Virginia Players’ and performed the title role in their production of Shakespeare’s Julius Caesar on February 5, 1938. In 1942, he married screenwriter Ruth Sacks , whose film "Mrs. Palfrey at the Claremont" was released in 2005 and won “Best Film in Japan” in 2010. Together the Caplins created a visiting artist fund for the Department of Drama at the University of Virginia in March 1999, enabling the department to bring in actors, directors, designers, and scholars regarded as leaders in the profession. He initiated several key projects as chair of the Council for the Arts including the Arts Enhancement Fund, which allowed department chairs and program directors to finance new arts initiatives. Under Caplin’s leadership, the fund raised millions of dollars, which resulted in the successful development of the Carr’s Hill arts district, later known as the Arts Grounds.
Bob Chapel, chair of the Department of Drama and chair of the Virginia 2020 Commission on the Fine and Performing Arts said, “Immediately after moving here in 1990, I met Mortimer and Ruth Caplin at the very first Arts Council meeting. From that moment, I was struck by their devotion to the all of the arts and their desire to do all they could to help foster their growth. Since that time, their unflagging support and their great generosity have done much to propel the development of all our arts programs to where we are today. Words cannot express how deeply I appreciate their substantial support for our guest artist program as well as their energy in promoting the Drama Department, the Heritage Repertory Theatre, and the future of a dance program at U.Va. All those involved in the arts at this University will be forever in their debt.”
