That's what Art says. I searched the death notices in Tucson, Arizona, but only found an official note for Helen Cronhein Foster Ziel, several years back. I would think Art would know, as he and Ron worked closely to document the LIRR. Ron was diabetic, and that he lived such an active life after being diagnosed in his twenties, is remarkable. While in my teens, Ron took me on my first steam safari to Steamtown in Vermont, and there I got a cab ride with Nelson Blount.
Ron's personality took some getting used to, but he amassed an enormous documentation of the Long Island Rail Road, and covered the last of the steam locomotives in their extermination phase. Credit where it is due.
His earliest book, The Twilight of Steam Locomotives" is a landmark book on the subject.
This is a sad passing.
