A celebration of Nestor's life was held at Duke on June 14th, 2015. I am thankful to my family and friends who joined us to remember Nestor.

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.

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.
