Since the death of our founder in November 2021, we have been gathering many heartwarming messages from around the world. As Shirley fought to help primates for almost 50 years, she  had a tremendous impact on humans as well.

Included in this issue of IPPL News are memories from IPPL’s board and staff, tributes from our Global Partners and other organizations, a letter from Shirley in a 2005 newsletter and more.

We hope you will enjoy reading the heartfelt comments from so many who helped create this special issue of IPPL News.

    I have received your tribute issue and I just wanted to let you know how very sad I was to read of Ms. McGreal’s passing. She was such and inspiration to everyone who met her. We have lost a wonderful human being and all the primates and critters she came in contract with will miss her terribly . I will be sending a donation in her honor. Sincerely Leonora Xhrouet
