Henk was born in Kalidjati, Indonesia (then a Dutch colony) on June 22, 1941 to Willem George Christian Tinkelenberg and Cornelia (VanOmmen) Tinkelenberg.

He graduated from Needham High School in 1958, and from the Massachusetts Institute of Technology (MIT) in 1962 with a degree in Theoretical Mathematics. Henk completed his Master's in Oceanography at MIT in 1964. He spent his professional career as a software engineering consultant with Holliston Computer Associates, one of the businesses he founded.

Henk is survived by his wife of 41 years, Kathleen (Carey) Tinkelenberg of Carefree, Arizona; his four children, William Tinkelenberg of Durham, Maine; Arthur Tinkelenberg (Stephanie Biedermann) of Oradell, New Jersey; George Tinkelenberg (Stephanie Maher) of Belchertown, Massachusetts; and Carey Tinkelenberg (Sean Wendt) of Minneapolis, Minnesota; sisters Carla (Thomas) Cross of Carefree, Arizona and Tina Braster of Phoenix, Arizona; grandson Henry Tinkelenberg of Oradell, New Jersey; and numerous nieces, nephews, and cousins around the globe.

Henk is remembered with loving admiration for his intelligence, wit, and ingenuity, for his resolve and his principled leadership, and for his influence on his family who will aspire to carry on his vibrant legacy.
