Peter Singer is a world-renowned philosopher and bioethicist whose writings have been foundational to both the effective altruism movement and the modern animal rights movement. Singer has authored and edited more than 50 books, including his seminal works on effective giving, The Life You Can Save: How to Do Your Part to End World Poverty (2009, 2019) and The Most Good You Can Do (2015). In 2013, Singer founded the nonprofit The Life You Can Save to help spread his ideas about effective giving and generate support for effective charities. In 2021, he was awarded the Berggruen Prize for Philosophy and Culture for his contributions to the field of philosophy, and he donated the entire US$1 million prize to charity. Singer currently teaches at Princeton University, where he is Ira W. DeCamp Professor of Bioethics at the University Center for Human Values. When he’s not reading or writing, Singer enjoys hiking, surfing, and spending time with his three daughters and four grandchildren.
