STEFAN JOHANNES KRIEGER '89mcl of Oakton, VA, died on July 8 of stomach cancer, aged 52. He earned his PhD in Economics in 1998 from the University of Chicago and worked as a theoretical macroeconomist for the rest of his career, first as an assistant professor at Yale University, then as a hedge fund portfolio manager. He ended his career at Freddie Mac, where among other work, he developed an industry-leading house price index that was at the core of Freddie Mac's mortgage risk modeling in the aftermath of the 2008 housing crisis. Born and raised in Germany, he was a dual citizen who cherished his European origins even as he chose to spend his adult life in the US. Economics was Stefan's first love, but his extensive book collection testifies to his other consuming interests: the sciences (particularly physics), mathematics, politics, history and law. He loved intellectual conversation as much as learning, and combining both with a mountain hike was his idea of paradise. He wanted to spend his later years with his family, visiting the world's natural wonders before they were lost to climate change. Stefan leaves his wife, Eliza Morss '86; three teenage daughters, Alexandra, Helen and Anne; his parents, Louise Asselin Krieger '63 and Wolfgang Krieger A.M. '64; a sister, Karin Kaldewey, a brother, Matthias; one nephew and three nieces.

A memorial service for Stefan will be held in Cambridge in October. For further information, please email Eliza Morss: eliza.morss@gmail.com.
