Klaus Boese (Böse), aged 86, died peacefully at home in Washington DC, on 28 January, 2026. He is survived by his wife of 60 years, Janet, their children, Kirsten (Ben Self) and Alexander (Beverley Walton), granddaughters, Astrid Self and Pippa Self, and step-grandson, Charlie Curzon (Danielle) and great-grandsons, Kingston and Rory Curzon, and a sister, Angela Boese.

Klaus was born in Bremen, Germany on 8 January 1940, under the shadow of World War II. The horrors of the war and the kindness of family and friends who helped his family rebuild in its aftermath had a profound impact on shaping Klaus' values and commitment to service. Klaus was a world traveller, who spoke two languages fluently and had a working proficiency in several others. He had a life-long interest in international politics.

He attended Hamburg University in Germany for two years and transferred to Yale University in New Haven. After graduating from Yale and the Johns Hopkins School of Advanced International Studies, he embarked on a career in finance. He was proud to spend the latter part of his career at the International Monetary Fund (IMF). While at the IMF, Klaus also served on the board of the Bank-Fund Staff Federal Credit Union, including as its President. Upon retirement, Klaus continued his service as Board Chair of the IMF Retirees Association. He joined the Tidewater Oyster Gardeners Association (TOGA), earning the certification of Master Oyster Gardener. He enjoyed travel, reading, and gardening, among other activities. He loved animals and the feeling was mutual.

He is remembered by an extended family of cousins, nieces, nephews and friends who mourn his death but are grateful for Klaus' dependable and loving presence in their lives.

In lieu of flowers, the family suggests a donation to a local animal rescue group, the World Central Kitchen, or TOGA in Klaus' name.
