Morris Mitler

In Memoriam

Morris Mitler was an economist in industry and financial analysis at the Investment Company Institute. He was a core part of the Investment Company Fact Book team during his entire tenure at ICI, and for two of those years, he directed the publication of the Fact Book.

Morris is missed every day by his colleagues, and his absence was particularly felt during this year’s Fact Book season. We devote many hours each year to putting together Fact Book, and a lot of that time is spent in deep collaboration with the entire team. We missed his friendship, his stories, his humor, his enthusiasm, his generosity, his humility, and his care for his work.

He was beloved by his colleagues. He was a friend to us all.
