I just learned of Ed's death today (7/11/2018) when I was browsing for the address of his website. It prompted many memories of things learned from him in the seventies. His teaching brought me into the modern world of programming. I am particularly fond of Ed's replacement of 'milestone' with the term 'inch-pebble," which I made use of often when asking programmers in my group for time estimates. He was a very intelligent man.

Just learned of this great loss. Ed Yourdon's legacy made a significant difference in the lives of many. His body of work influenced my career, and his pioneering work influenced how I think. I was fortunate to work at Yourdon, Inc with a talented, curious and innovative team, touched by Ed's genius and entrepreneurial spirit.
To Toni and the family, my deepest sympathy. Keeping you all in my prayers.
May Ed rest in peace.

Late to the sad news; I was able to thank him for a terrific photo on the 1 & 2 line platform, an exemplar of my daily grind. And for his influence on my career.

I worked for Yourdon Inc when I first moved to Northern VA. Had the pleasure of meeting Ed a few times. Years later, connected with him on the internet and to my astonishment, learned we'd both lived in Northport and graduated from NHS, although at different times. We had many of the same teachers and reminisced about NHS. Luckily, I got to know him as a friend and was impressed with his photography. I was shocked to learn of his death. RIP, Ed - you are missed. Sincere sympathies to Toni and all other family members. "Only the good die young."

Very sad to hear of Ed's passing. He was truly a friend and mentor to many of us who were touched by the Yourdon organization. Careers were started and the course of software development was changed profoundly by Ed and his associates. I will never forget my days at Yourdon, Inc. and the amazing colleagues there. My deepest condolences to Toni and the family.

A shock to learn that Ed Yourdon has passed on. My life changed dramatically in the Fall of 1998 when I stumbled on Ed's forum for his Y2K book. The intelligent prodigious generous practical knowledge shared by 1000s of ppl in many walks of life on that forum was a unique experience in history. It took off fast n furious so Ed recruited Admins. I was one. 100s of emails and discussions behind the scenes in addition to 1000s of threads. Heady amazing times, and Ed's brilliance was abundant. Many years of 16 hour days. Ed's impact on planet earth is enormous. I'm sure Ed is not resting in heaven but is very busy there pursuing his interests and sharing generously.

So sorry to hear of the death of Ed Yourdon. Blessings to his friends and family. One of his books was the first I read cover to cover in my profession, learning structured programming and DFD's, with others right here on my shelves too. Rest in peace.

As I looked at Ed's bibliography, I realized that I owned almost all his books. Not just read them, but owned them. Some of them in multiple editions.

Ed was a great influence on my career in methodologies. And later, on my love of art and photography. I loved that he shared his works on social media.

It was always a joy to get a chance to chat with him at events, then later on Twitter.

I'm off to find a book and spend some time with him again.

My heartfelt condolences go to the family. Ed has been a source of professional inspiration for me. His "Death March" Book really helped me while I was in such a situation. Later on I admired Ed's artwork and was happy to see him explore Street Art in Berlin.
Hence I will send a little street scene from Berlin - he could have loved that

I was surprised and saddened by the news of Ed's death. He was one of the pioneers who helped define and legitimize an organized approach to software development. In addition to his own books Ed's company published books by other authors in the field and nurtured the development of several software engineering disciplines.

Most of us get to impact a small circle of family and friends in our lifetime. Ed was not most people. He generously shared his gifts and art with the world so that others could benefit. He will be missed.

My Sympathies to the family and friends of Ed Yourdon. He was a strong advocate for professional developers, when many others thought it was "just coding". He understood the importance, value and difficulty of good software. I always enjoyed our conversations when our paths would cross at conferences. May he rest in peace...

My heartfelt condolences to the family... I have known Ed for over 30 years, his work in software engineering stands on its own merit and his effect on the lives of those he encountered, including mine, was profound. Publisher, methodologist, fellow expert witness, talented photographer, and friend - we will miss you, Ed.

My picture on my book.
His book, Structured Design had two effects: one, it completely re-directed my career. And it made me want to write a book that did that for other people. I will be forever grateful.

My condolences to the family of Ed Yourdon. I studied Mr. Yourdon's programming and software development techniques in college in the 1970s. I followed his writings in support of programmers through the 80s, 90s and Oughts. He will be missed.

I learned and practiced Ed's principles of software analysis and design when I was in college 25 years ago. To this day, I continue applying these principles as a Software Architect. My Condolences to his wife and their family.

I worked with Ed at Comshare Inc., in 1968, where he gave me one of my first programming assignments. I learned a ton from him, and I've always been grateful for that experience.

Hope you can rest Ed. We first met on a Fire Island ferry decades ago. First we thought our only common interest was that beach. We learned we had connections tied to publishing and technology. Peace, John

Ed's early work on popularizing software analysis and design methods was very influential. His talks were well-organized, entertaining, and frequently filled with images of great art. He reached many thousands of software designers through his early books and courses. More recently, I enjoyed his Flickr page filled with photos of the Upper West Side and his family's travels. Condolences to his wife Toni and their family.

I met Ed well after he had achieved his reputation in the software industry. I was editing a magazine for PC programmers and doing my best to translate Ed's legacy into language that would allow a new generation to benefit from his insights. He was generous with his time and advice, and he even wrote for us. He was a man of great spirit, and the world is diminished upon his death.

To this day, I still tell people how lucky I was to work for Ed Yourdon. He was a shining example of a boss who was a friend. I was teaching at a client near NASA on 9/11 and Ed was the first one (other than my sons) to reach out to me to be sure I was ok---this over 15 years after I left working for him. Now, that's a mensch. RIP friend and mentor. I will miss your great pictures.
