Klaus Jon Lowenstein

Klaus was a lifelong learner, an enthusiastic social connector, and a man who seized every opportunity for enrichment and experience. Klaus was intentional in the ways he stayed in touch with friends and family both near and far. He was a world traveler who loved sharing his stories (often more than once), offering his strong opinions (whether requested or not), helping others, and enjoying his favorite wines, particularly those from the distinguished vineyards of Charles Shaw.

His life read like a chapter from the history books. Born in Giessen, Germany, Klaus fled Nazi persecution in 1939. At just ten years old, he was among the many children evacuated from London during the Blitz. He never forgot the kindness and safety he found in Braunston, England, where he learned English, played soccer, and proudly served as a plane spotter for the RAF.

In 1943, Klaus immigrated to the United States with his brother Manfred and their mother Martha, reuniting with his father Julius. They began again, this time in peace. Klaus thrived in Wilmington, Delaware, graduating from the University of Delaware with a degree in chemistry before serving two years in the U.S. Army. He was deeply proud to be an American and believed strongly that the country should always be a safe haven for all people.

Klaus later moved to the Boston area to build a career in industrial coatings, eventually becoming the successful owner of Bay State Chemical. In Cambridge, he met his wife, Elaine. Together, they raised their two sons, Eric and Andrew. Klaus and Elaine laughed loudly and often, delighting in each other’s company, and were known for their parties.

In 1984, Elaine’s death from cancer changed everything. Those who have raised children can fully understand the weight Klaus carried in navigating that loss while continuing to guide his family. He did his very best.

In 1993, Klaus returned to Cambridge, a city he loved. He biked and walked everywhere, rarely missing an opportunity to attend a free concert, a public lecture, or a BU Evergreen course. He mentored immigrants from Russia and became a trained mediator, always eager to connect, help, and learn. His travels continued, taking him to the Pyramids of Giza, as well as China, Thailand, Argentina, Italy, Eastern Europe, and back to his hometown of Giessen.

In his later years, Klaus embraced one of his favorite roles: grandfather to Quinn, Eben, Jack, Cal, and Lainey. He delighted in their curiosity and energy, and they in turn cherished his humor, remarkable memory, and warmth. His life, and the way he lived it, with curiosity and resilience left a lasting impression on all who knew him.

Thank you, Klaus.
