“It is with great sadness that we share the news that our husband and father, David Koch, has passed away.
“He died peacefully at home, surrounded by his wife and children.
“While we mourn the loss of our hero, we remember his iconic laughter, insatiable curiosity, and gentle heart. His stories of childhood adventures enlivened our family dinners; his endless knowledge rendered him our 'walking Google.' His sensitive heart had him shed a tear at the beauty of his daughter’s ballet, and beam with pride when his son beat him at chess. We will miss the fifth link in our family.
“Yet, we wish for all to celebrate the life and impact of this most generous and kind man. He believed he had a responsibility to a world that had given him so many opportunities to succeed. David’s philanthropic dedication to education, the arts and cancer research will have a lasting impact on innumerable lives - and that we will cherish forever.”
