Hadsell, Robert Melvin

January 10, 1942 - March 19, 2021

Robert Melvin Hadsell, age 79, died at Plano, Texas on Friday, March 19, 2021.

Born January 10, 1942, in Schenectady, New York, he was valedictorian of Mohonasen High School’s class of 1960, the school’s first.  He graduated from Cornell College in Mt. Vernon, Iowa, and received a Ph. D. in chemistry from Northwestern University.

He used his talent for scientific writing in a career disseminating highly technical information to a general audience for the American Chemical Society and the National Cancer Institute in Washington, D.C., for Fox Chase Cancer Center in Philadelphia, and for the University of Texas Southwestern Medical Center in Dallas.  He developed courseware (computer-based instruction) for Mountain View College in Dallas and for various employers.  Most recently he was a social media influencer for Dallas’s jazz scene.

Robert is survived by his brother Richard of Cortlandt Manor, NY; 4 sons: Jeffrey Hadsell of Oakland, MI, Gregory Hadsell of Mill Valley, CA, Ethan Hadsell of Albuquerque, NM, and Lucas Hadsell of Austin, TX; 4 grandchildren; 3 nieces and a nephew; and a multitude of cousins.

All who knew Bob will miss his wry wit, his generous heart, and his love of the performing arts.  He loved music — musicals, jazz, theater, the clarinet, and those who shared this love.

My sincere condolences for your loss. I went all the way through school with Robert, lived in the same neighborhood and was frankly in awe of his ability to absorb all that we were being taught…. fast forward 50 years and we sat side by side at the 50 year reunion…a life well lived.

My deepest sympathy for all the family on losing Bob way before his time . . . . My heart goes out to all of you. <3

Eric Brown says:

Bob was a year ahead of me at Cornell College and his brother, Dick, was a year behind me. Bob and I had great times together as fellow clarinetists in band and orchestra. Also, as members of the Men’s Honor Residence. And, as members of the Cornellian staff. Noteworthy, is that Bob was the Cornellian Science Editor, an experience that foretold his future career. (On the other hand, I was the Cartoonist, which foretold little about my mine.) My deepest sympathy to brother Dick and the Hadsell family. I am so sorry for your loss.

I’m very sorry to hear that Bob has passed away. My sincerest condolences to his family and friends. I first met Bob when We were both five years old. We lived on the same block, were in the same classes at school, and drawn together by shared interests. He was an important part of my childhood and adolescence, and I’m sure I was an important part of his.

Joseph Keane says:

I was saddened to learn of Bob’s passing. Bob and his brother were neighbors of mine in Schenectady and we travelled through grade school and high school in the “50’s” My sincere condolences to his family and to Richard.

Nancy Vick says:

My condolences to Dick and the whole family. What an amazing duo of musical and science stars you brothers must have been. My thoughts are with you.
