Memories / Herinneringen

Matt Prestegaard – 21 November 2025

I hope Jack found some comfort in the days before, and that you find some measure of comfort in the days to come. I was pleased to hear that Martin and Hans-Peter had recent chances to visit. I loved seeing what was done with bmdw.org.

Some moments from our trip to South Africa come to my mind:

  • Jack working on capturing lightning with his camera during one of the barbecue nights
  • My wife Jen accidentally grazing Jack’s lips while attempting the dutch kiss for the first time

Our work took us around the world, but it was your friendship, kindness, and passion for photography that made those trips unforgettable. I am grateful for every moment we shared and will carry those memories with me always. I am honored to have called you both a colleague and a friend, and you will be deeply missed.

Pam R – 20 November 2025

Not only was Jack brilliant, he was such a warm and compassionate person and colleague. He was always ready with a warm smile, uplifting greeting and a genuine interest in others. Missing you already.

Twenty seven years of memories are not easy to summarise in one sentence!

Like a candle, the light of a good heart never truly disappears. I will always be grateful for his integrity, respect and passion.
