Dear Katie, I didn't know your father but if the saying, children are a product of their parents, then he must have been an amazing gentleman.

To the extended Gannon Family:

I was saddened by the passing of my friend and mentor, John Gannon. I first met John who, was teaching the class in "Stream Sanitation" with Clarence Velz in the early 1960s in the SPH at UM. John participated for many years in the Science Advisory PaneI for Crystal Lake (Benzie Co.) His classic water quality study of Crystal Lake (1970), was inspiration for my own professional and avocational careers. I quoted extensively from his study in my own book, The Comedy of Crystal Lake (2015), which I had the privilege of sharing with John My sincerest condolences.

To the Gannon Family: Jill and John express their sincere condolences to the family of an American Hero, who, as mentioned in his Obituary, served his country with great distinction, his profession, his community, and above all his family. Mr. Gannon did live a long life, more than 40% of the life of the USA. He witnessed many changes to our world and leaves a legacy of his family to continue his service to others.

The Manhattan College alumni community shares the grief, and is now praying for our fellow alumni and the family at this time. The Alumni Office has been informed. As well as the Jasper Jottings community that I personally can reach. We are all a little poorer now. "No man is an island, entire of itself ... any mans death diminishes me". We are sorry for your loss.
