Personal Background

Eugene Edward McDonnell (October 18, 1926 - August 17, 2010) was a Computer Science pioneer and long-time contributor to the programming languagesAPL and J.
He was a graduate of Brooklyn Technical High School. After serving as an infantrycorporal in the U.S. Army in World War II, he attended the University of Kentucky, graduating in 1949 summa cum laude, and was elected to Phi Beta Kappa. He was awarded a First Year Graduate Fellowship to Harvard University, where he studied comparative literature, particularly DantesDivine Comedy.
Studying the poems of Robert Frost, he noticed that the first two poems in Frost's book West Running Brook, "Spring Pools" and "The Freedom of the Moon", not only discuss reflecting, but the rhyme schemes of the two reflect each other: aabcbc and cbcbaa. When he met Frost, he was delighted to find that they had both committed the 193 lines of John Milton's "Lycidas" to memory.
His first work at IBM was in the design of IBMs first Time-Sharing system, which became a very early host to IVSYS, a predecessor of APL. In 1968 he became a colleague of Ken Iverson, used Iverson notation before APL was named, and was active in the very earliest days of APL. He holds U.S. Patent 3,400,376 (3 September 1968) "Information Transfer Control System" allowing communication between two users. In 1978 he left IBM and joined I. P. Sharp Associates. He retired from I.P. Sharp in 1990.
At IBM, McDonnell devised the notation for the signum and circle functions in APL, designed the complexfloor function, and proposed the extension of or and and to GCD and LCM. With Iverson he was responsible for the inclusion of hooks and forks in J. The result of zero divided by zero in J is as he proposed in 1976. He won the Iverson Award in 1987.
McDonnell was the publisher of the APL Press, producing "A Source Book in APL" and "APL Quote Quad, the Early Years". He was the editor and principal contributor of the Recreational APL column in APL Quote-Quad for many years. He wrote dozens of the "At Play with J" columns in Vector, the journal of the British APL Association. He contributed to Sloane'sOn-line Encyclopedia of Integer Sequences.
He had Erdős number 2:
- Paul Erdős and Jeffrey Shallit, New bounds on the length of finite Pierce and Engel series, Séminaire de Théorie des Nombres de Bordeaux 3, 1991, pp. 4353.
- Eugene McDonnell and Jeffrey Shallit, Extending APL to Infinity, Proc. APL 80 International Conf., North-Holland, 1980, pp. 123132.
He was a member of the Jane Austen Society of North America (JASNA), and gave a talk "Classical Persuasion" at the JASNA meeting at Lake Louise in 1993. He was active in the Bay area Jane Austen group, and wrote a topical index to the Dierdre Le Faye edition of Jane Austen's letters, which can be seen at the Pemberly site, http://www.pemberley.com/.
McDonnell died peacefully at his home in Palo Alto in 2010.

For Eugene's Family - I am very sorry for your loss. Eugene sounded like a wonderful husband and father. My heart goes out to you. The Bible can be a great source of comfort during times like this. The resurrection is a sure hope found in the Bible. There are several accounts found in it where people who had died were brought back to life as humans on earth. The most well known being that of Jesus' friend Lazarus. This will happen again but on a much bigger scale. At John 5:28,29 Jesus said "The hour is coming in which all those in the memorial tombs will hear his voice and come out." Jehovah's original purpose was for us to live forever on a paradise earth. That has not changed. At Revelation 21:3,4 Jehovah God promises to wipe out every tear from out eyes. There will be no mourning, no outcry, no pain, and no death. Isn't it comforting to know that seeing Eugene right here on this earth can be a reality? It should also be comforting to know that the pain you feel from loosing him can be undone. The promises found in the Bible that Jehovah has made are sure to come true because in the book of Titus chapter 1 it states "God cannot lie." I know this wound is still very fresh. Hopefully this brings you some comfort. Please feel free to contact me. My email address is Futurehope4u09@yahoo.com. - from Amanda
condolences for Jeanne - Dear Jeanne, I only met your husband at one or two social gatherings, so didn't have the privilege of really knowing him, but the heartfelt tributes here speak well of him. My husband of 38 years died last May, so I can empathize with your loss. I used not to think that sympathy cards and letters were significant, but I've learned the contrary, and just wanted you to know that someone is thinking of you. - from Meredith Phillips
The McDonnell family in a phrase - After seeing all of the extended McDonnell family on Sunday I could only think of one phrase "What an incredible Gene pool" - pun intended:) - from John van Gelder
My Father - My father's mother was Helen Julia Powers and her nickname was "Happy". I'm proud to have her name although she died before I was born and I never met her. He always said he inherited the happy gene from her. He truly was a happy man. Freud said "Love and work are the cornerstones of our humanness". Eugene loved his work and the intellectual interplay he had with his colleagues. But he was home every night by 5:30 and he was a husband and a father then. It was a gift to have a father who was so happy in his career and had work in its rightful balance in his life. He wasn't perfect. He could be so intellectually competitive he could actually relish creaming a child or adolescent at a card game or board game. If he was cooking a meal you couldn't be in the kitchen with him--he had to have complete control over every aspect of it. As a teenager I found it hard to be close to him. But as an adult I saw so much of how he molded all of his children by his example for which I am forever grateful. He was completely honest, moral and ethical. My parents accepted all of their children for who they really were. And till the very end he was so proud of all of us. We weren't raised with a lot of discipline but with trust and respect. What a gift in life to be able to be who you are and be loved for it. He was a great example of someone who lived in gratitude. Thank you Dad for the love and acceptance and for the example of how to live. I have been so blessed to be raised by you. - from Julia Powers
Latest Memories
Cayle - YouÂre a real deep tihnker. Thanks for sharing.
David Hanna - When the Negro Leagues baseball traveling exhibit brought me to San Francisco, I knew it was an opportunity to reconnect with family, but it was much more. With Uncle Oogie, in that brief time spent together, I saw a truly happy man, full of life and energy that a man half his age could only hope for. He shared stories of growing up a Brooklyn Dodger fan watching Jackie Robinson break the color barrier which was always important to me because I was a Dodger fan from a young age and I often thought about what it was like to go to Ebbets Field. I will never forget the glimmer in his eyes as he talked about those days.
John van Gelder - As a Palo Alto High School student, Gene ( or did we call him Mr. Mc Donnell? I forget) was a great mentor to all of Jim's friends including Peter, Abdul, Andrew and myself. He aloud us to test out his book on APL in their work environment and was instrumental it launching my and Abdul's career. He was the 1st software professional I ever met. My Dad was a hardware guy, so now I write software to design, test, and manufacture Intel's latest processors. Gene and Jean opened their house to way too many late nights of Theatrical Bridge for many years. They also lent Jim the family car by 16 so we could go all over the Bay Area from Los Gatos to San Francisco at ungodly hours of the night. I guess they thought we would be safe in their car or in their house. I think they were right. Good times and good memories. Thanks to the entire McDonnell family.
Jeannie Farr Starkey - Uncle "Oogie" as we called him taught me about the degrees of separation. When I was a little girl he told me that because I shook his hand, I was only three handshakes away from President John F. Kennedy and of course explained how in great detail. I remember being fascinated by that. He always shared some interesting and fun facts. The last time I saw him and Aunt Jeanne was here in Ohio last summer. He told us what each one of his children were doing at the time, again in detail, and at the end he said words I wish could remember exactly but to the effect, lots of children happy life, and I remember thinking to myself, that is a happy man...I have thought about that many times since
luke mcdonnell - Once,as a child, in the midst of stuffing my face with some confection, I said, "Deep down in my heart, I really don't like chocolate!" Dad though that was so funny, it became a sort of motto for me; every time the subject of dessert came up, dad would deliver the motto!
