Nestor Schmajuk Obituary

Nestor Alberto Schmajuk

November 23, 1948 - February 16, 2015

Palo Alto, California

Nestor Schmajuk died on Monday, February 16, in Palo Alto, California.

Nestor was born in Argentina in 1948 to Norberto Schmajuk and Carolina Schachter, Polish immigrants who fled to Argentina before the start of the second World War. Nestor had a younger sister, Monica, and grew up in Buenos Aires, where he made trouble in school, played soccer, and organized movie clubs for his friends. His uncle Salomon Schachter was a great influence on him. He studied electrical engineering, worked at his father's wheel factory, Pulmania, and met his future wife, Mabel Tyberg. He became an Associate Professor of Biomedical Engineering at the University of Buenos Aires.

In 1981, Nestor and Mabel and their two daughters, Gabriela and Mariana, moved to Binghamton, New York, for Nestor to pursue a fellowship in neuroscience. After two years in snowy Upstate, the family moved to western Massachusetts. In 1986, Nestor obtained a doctorate in Psychology from the University of Massachusetts and became a postdoctoral fellow at Boston University. From 1988 until 1993, he was an Assistant Professor of Psychology at Northwestern University.

The Schmajuk family moved to Chapel Hill in 1993. Nestor became a professor at the Duke University Department of Psychology and Neuroscience. He taught there for more than 20 years. His professional interests focused on developing and testing neural network models of classical and operant conditioning, animal communication, creativity, and spatial learning. He authored 4 books on animal learning and founded the Society for Computational Modeling of Associative Learning.

Nestor loved Schubert and Dvorak, Johnny Cash, Car Talk, playing the recorder, and brushing his teeth. He taught his daughters that girls can do anything and that they should avoid carrying a purse. He was a clown and always the contrarian. He had a habit of tossing a glassful of water across the dinner table if anyone had a particularly funny wisecrack. He took a nap at the movies every Saturday night and was a chronic whistler.

In 2012, Nestor suffered a stroke, but fulfilled his dream of retiring to California to be near his family and only grandson, Henry.

A memorial service in North Carolina will be held in the spring, time and place to be determined. Please email [email protected] to receive an announcement.

In lieu of flowers, donations may be made to Duke University (for line: c/o Department of Psychology & Neuroscience), and mailed to Trinity College Development, P.O. Box 90429, Durham, NC 27708.

We met in the early '80s at the and in the Instituto de Ingeniera Biomdica (IIBM). At that time, he was developing a new line of study of behaviour in toads. We met again in that Instituto de Biologa y Medicina Experimental (IBYME) after getting his Master at SUNY, and was about to go to do his doctorate at the University of Massachusetts. At that time, I had the pleasure of exchanging ideas about psychology and computation neuroscience with him. It was his specialty and he was one of the first researchers to develop the area.
In the 1993, when he was already a brilliant researcher, Assistant Professor of psychology at Northwestern University and was beginning his career at Duke University, we met again in the IBYME. At the time, I got my Ph.D and had won a scholarship to do a postdoctoral experience. After finding the great coincidence on scientific objectives I had the honor of working in his laboratory for two years and began a friendship that continued until his departure. Nestor was a prolific and tireless worker and always attentive to his family. While it is not already present among us, I want to remind Nestor in the way he would have wanted: with joy and deep dedication to work.
Silvia and my thoughts are with Mabel, Gabriela and Mariana.

Mable, seeing Nestor's picture reminds me so much of seeing the two of you out for a walk in the neighborhood - he always had that mischievous smile, like a school boy ready to pull a prank. You knew if you wanted to see an extra twinkle in his eyes, you only needed to ask about Henry or about the girls.
This kind, gentle man will be missed.
Love and hugs, Kaye and Terry

I am so profoundly sorry for your loss and share in your sorrow and grief.

February 23, 2015

Dear Mable and Gabby,

I was deeply saddened by the news of your husband and father's passing. Our heart felt condolences to you and yours.
No word can reduce your pain, but passage of time will; give yourself time to heal.
There is nothing to replace your loss, but take comfort in what Helen Keller once said;
"What we have once loved and enjoyed, we can never lose. All that we love deeply becomes part of us."
My thoughts are with you

I met Nestor once, during one of his visits to London where I work as Reader (our funny way of calling a full-professor-in-waiting in the United Kingdom) in Computing.

He proposed me to co-edit a special issue on computational models of classical conditioning for the journal Learning & Behavior. For this he was seeking the collaboration of a computer scientist with knowledge in associative learning rightly or wrongly he thought that I was the person for the job. Someone, perhaps Geoff Hall himself, editor of the journal and a good friend with whom my partner, Esther Mondragon, had worked in York, passed on my name.

I was expecting a formal interview and given Nestor's status I must confess I was wary. I didn't know that Nestor was Argentinian and took me by surprise welcoming me in Spanish De modo que usted es vasco, verdad? (so you are Basque, right?). We went to the little cafeteria at UCL and talked about his two passions, family and work. In that order. I was immediately captivated by his gentle manner, his closeness, and the sharpness of his views.

During the editorial process across the pond we became friends. He was obsessed with detail, a trait that I share, and terribly honest, with his own work and in reviewing our colleagues'.

His career as a neuroscientist was heavily influenced by his training as an engineer in that he championed that models should be described formally and that they should be evaluated in a rigorous manner. His main goal was to formulate a standard model of associative learning, one that would account for all aspects of classical and operant conditioning.

His last model covered 82 of a list of classical conditioning phenomena that we compiled with Alan Wagner and Jose Larrauri for the special issue. But he was insatiable. We were working on an extension of his model when he suffered the stroke. Since then, our communication went through his wife, Mabel. From our correspondence I know that Nestor was a very lucky man.

I learned that Nestor had retired as I was preparing a talk for the annual conference of the Spanish Society for Comparative Psychology. Armando Machado was chairing it and Alex Kacelnik was one of the invited speakers. Armando had been a PhD student of Nestor's and Alex a colleague back in Buenos Aires. We knew that some of his best friends, Mauricio Papini, Gonzalo de la Casa, would be there, and decided to pay Nestor a tribute. It was a small, unpretentious event, yet enough to see the deep respect and fondness that people felt for him.

Our thoughts are with Mabel and the rest of Nestor's family.
