Manuel Silva Suárez

He tenido la oportunidad de compartir con Manolo 8 años en la Academia de Ciencias de Zaragoza y comprobar su bonhomía y su valía. Son momentos difíciles para todos y especialmente para la familia.

Como primero antiguo alumno de Manuel Silva y luego compañero de trabajo, expresar mis condolencias a la familia. Fue un gran profesor y un buen compañero.

Siento muchísimo la pérdida tan grande que ha supuesto el fallecimiento de Manuel. Lo conocí en mis últimos años de gestión universitaria y disfruté, cuando pude, de su conversación y conocimiento. Mi más sentido pésame para su familia.

Magnífico profesor y excelente persona. Nos trasmitió su pasión por la ingeniería. DEP

Manuel's death is a great loss. He has been one of the most visible and vocal Petri net researchers and, for many years, a key member of our Petri Net Steering Committee. He introduced Petri nets to the Spanish research community and made Zaragoza the epicenter of the "structure theory for Petri nets". He also helped to promote Petri nets in manufacturing, performance analysis, and discrete events systems. We will miss him. My condolences to family, friends, and colleagues.

Excelente docente, ingeniero, humanista, académico, gestor ... y persona. Creo que todos los que hemos coincidido con él en alguna de sus facetas hemos quedado positivamente impactados. Una gran pérdida para la Universidad de Zaragoza, EINA e I3A, pero una enorme suerte haberlo tenido todos estos años.
Un abrazo para toda la familia.

Ha sido para mi un privilegio conocer y colaborar con el Prof. Silva, pero sobre todo contar con Manolo, durante treinta años. Deja un hueco ireemplazable y un recuerdo imborrable. Mi más sincero afecto a Regi, a sus hijos y familiares.

Siento muchísmo su pérdida y lo echaremos de menos. Recuerdo con mucho cariño los dos años que compartimos en la Dirección de la entonces ETSII y luego CPS. Aün no me creo que se haya ido tan pronto. EINA no seria hoy lo que es si no hubiera sido por su impulso y su gran visión. Un fuerte abrazo

Tempus fugit, sí, pero no lo parece cuando se echa la vista atrás y se ven las dimensiones de lo realizado y lo creado, la inmensidad del legado que nos deja, para el que harían falta varias vidas extraordinarias. Aunque a Manolo le bastó con una, tristemente truncada tan pronto, y aún tuvo tiempo para ser, además, cercano, divertido y generoso como pocos. Pero sí, tempus fugit, parece que todo fue ayer, y de repente nos hemos quedado tan solos. Descansa en paz, tu recuerdo nos acompañará siempre.

Manolo, ejemplo para muchos...nos acompaña su alegría siempre inteligente y su visión siempre buscando horizontes

Over several decades Manuel has been tremendously supportive to the worldwide research community working on Petri nets. In particular, he has made great contributions to the organisation of Petri Nets conference series and the activities of its Steering Committee. He will be deeply missed as a friend and colleague with whom it was always so rewarding to meet and discuss science as well as ordinary life related matters.

My sincere condolences to Manuel's family and to his close friends during this difficult time.

I fondly remember Prof Silva as a great human being, caring colleague, beaming with knowledge he shared with kindness and wisdom. He made tremendous contributions to Petri nets and the community. My deepest condolences to his colleagues and family.

I am very sad to learn Manuel's disparition. He was a mentor for our community but also an "excellent friend" with a vast culture and never out of energy. I remember of him since the very beginning of my carrer.

Please provide my sincere and deepest condolances to his family and colleagues

I feel very sad about losing Manuel. He has always been a role model to all of us, as a brilliant mind and most enthusiastic researcher, but also as a wonderful friend, always so warm and accessible!

My most recent memories of talking to Manuel go to the Zaragoza Petri nets conference a few years ago, when I had a pleasure and honour of sitting next to him and his wife at the banquet.

Sincere condolences to Manuel's family and everybody who was close to him, both personally, professionally, and spiritually.

Triste noticia y mis condolencias para la familia. Saludos de un recién llegado a Grenoble, en el año 1975, viniendo de Colombia al programa de "D.E.A en Informatique".

Outstanding Professor with a great personality.
Thank you so much for all of your contributions.
Dear Professor Silva Rest in Peace

I extend my deepest condolences to his family and colleagues.

We lose a great researcher and friend who inspired many of us.

It is with great regret that I receive this news. I had the pleasure of meeting and working with Prof. Manuel Silva in the dissemination of works on discrete event systems and Petri nets, mainly in institutions in Latin America. Much more than an example of a researcher and teacher, he was a very pleasant person who greatly animated any environment.
"Minhas condlências à família"

A great loss to science.
My sympathies to your family.

As minhas condolências a todos os amigos e família.

Manuel Silva fue, junto con Jorge Júlvez, mi director de doctorado. Como le dije los agradecimientos de mi tesis, "Gracias a Manolo, que has estado ahí siempre atento, con tu capacidad de abstracción y tu memoria infinitas. Con cuidado de que no nos metiéramos en terrenos demasiado ásperos o que no tuvieran la suficiente relevancia. Siempre planificando y pensando en qué hacer después."
Manolo tenía una mente privilegiada, una capacidad de trabajo exagerada. Tenía muy buena intuición, sensibilidad y una envidiable forma de disfrutar/aprovechar las oportunidades (Entre ellas sus postales de navidad, en las que siempre soñar con un mundo mejor).
Me siento muy afortunada de mi etapa de doctoranda y de haberlos tenido como directores.

Pocos Ingenieros Informáticos de mi promoción lo conocíamos, pero su legado llegó a todos, ya que él fue uno de los fundadores del DIIS, él dirigió la tesis de muchos que luego serían nuestros profesores de informática, y también él puso los cimientos de la Escuela de Ingeniería/CPS (quien por ejemplo ideó los "días de cambio" que tan creativos y útiles nos parecían).

Mis sinceras condolencias a Regi, Manu y Alex, a quienes seguro que la investigación os robó muchas horas, pero a quienes siempre os tenía presentes (y de quienes presumía cuando tenía ocasión). ¡Un fuerte abrazo!

Un fuerte abrazo a su señora esposa e hijos. Un gran ser humano deseoso de compartir sus conocimientos con todos nosotros. Lo recordaré en sus visitas a Guadalajara, México y en aquellas ocasiones que platiqué con él en Palma de Mallorca y Reims. Deja un gran legado.

Very sad news! I remember Manuel from several meetings, starting with a PhD defence (Javier Esparza) in Zaragoza, and continuing all through our careers. I remember all those Spanish guys sitting around a table after the defence, eating very nice Spanish food (grilled tomatoes and so on) and Manuel happily joking amongst them. We then met various times during the Basic Research projects DEMON and CALIBAN where I learned about the very nice Spanish work on linear algebra, traps, and all the rest of it, which was influenced very much by Manuel, if not even initiated by him. I also admire very much his ability to attract a bunch of excellent students, many of whom are now in senior positions. I also remember fondly his lectures given in English, some on "passing messages", which sometimes sounded like "passing massages" to my ears. It is only a week ago that I re-read parts of his TCS paper of 1997 because I wanted to know what exactly was the statement there about the realisability of (minimal) T-invariants. Unfortunately now, Manuel must be, and is, sadly missed. My condolences go to his family and to those nearest to him.

I met Manuel in 1986 in Oxford when attending my first international conference and had the chance to discuss with him about my work in such a way that I could improve it.. Since then we had several joint works and every time, I was impressed by his deep understanding of fundamental problems in our field. In addition to be an outstanding researcher, he was very kind and always took care of me during my sojourns in Zaragoza. My condolences go to his family and to those nearest to him.

Un fuerte abrazo a la familia. Manuel ha sido un gran referente internacional, y un faro a nivel nacional de cómo hacer investigación de impacto. Su legado es difícil de igualar. Mucho ánimo.

Dear family of Manuel Silva, this is very sad news to hear that Manuel, a great Petri net scientist who has influenced so many of our academic lifes, has passed away. I still remember meeting him during the Petri nets conference in Japan in 1996 (after reading his many papers for my PhD work), when he invited me to visit his research group in Zaragoza. I took this chance a little later for some months, and still Zaragoza feels like a "second scientific home" for me because of that great time. The research topics and collaborations started by that (and the little spanish that I learned back then) still influence my research work. I will always admire how Manuel was keeping such a friendly and open atmosphere in research collaborations.
He will be missed, condolences to his family!

I am very sad to learn of Manuel's passing. He was both very competent and extremely open-minded, with an exceptional seriousness and kindness. I would like to send my sincere condolences to his family.
