PETER FLACK Obituary

FLACK--Peter, 92, of Hanover, NH, formerly of Manhattan, passed away peacefully in his home at Kendal of Hanover on December 12th. Born in Vienna, Austria in 1928 he fled to England on the last Kindertransport and then to the US in 1945 with his mother Gertrude Flack Danziger. He suffered many losses due to the Holocaust, including his beloved father, Hans Flack, but never lost his optimistic outlook and joie de vivre. Peter helped to support his mother while working during the day and putting himself through night school for engineering. He ultimately was the founding partner of the renowned national and international Consulting Engineering firm, Flack & Kurtz, acquired by WSP. While a successful businessman, Peter was most known for his love of his family, especially his wife of 65 years, Marianne "Schnaki" (nee Mosbacher), who predeceased him in February 2019, his grandchildren Emma and Jack Geduldig, and his adoring daughters Jennifer (Geduldig) and Stephanie Flack. He will be deeply missed by all who knew him but mostly by his family who could not love him more. Memorial contributions may be made to the Central Park Conservancy or the U.S. Holocaust Memorial Museum in Washington, DC.

Peter hired me with no experience, as the marketing director for Flack and Kurtz. He called me a diamond in the rough when he introduced me to Norman. I was young and didn't really understand how important and wonderful these two legends were to design, to NY, and to me. I think of these two mentors quite a bit. Peter shared stories, memories and gave me strength. I think of how fortunate I was to work for him, to laugh with him and to marvel at his successes. Thank you Mr. Flack.

No one can prepare you for a loss; it comes like a swift wind. However, take comfort in knowing God is with you and your family lean on him in your time of need. Please accept my most heartfelt condolences.

Peter Flack was a brilliant leader, a courageous man, and the leader in applying ecological solutions to engineering problems. Although coworkers I regarded him as a friend. My condolences to his daughters and his entire family. May we continue to find joy in his memory.
