Obituary for Henry Richard (Harry) McCanless

Harry McCanless died unexpectedly and instantly at home in Laguna Hills , California on Oct 7th from a massive heart attack. Harry is survived by his longtime companion and husband of over 23 years, Mark Coolidge; by his loving brother, Ed McCanless; by many loving cousins; and by many friends in cities where he lived, worked and visited. Harry was one of a kind, a dear person who will be missed by all who knew him.

Harry was born on Dec. 20, 1950 in Minneapolis, MN. As part of a military family, it was not until he was 7 years old that the family settled in Greenville, SC. Harry attended school there, graduating from J. L. Mann High School in 1968 and was one of the school’s first National Merit Scholars. In high school Harry excelled in math and sciences, track and swimming. From there he went on to Georgia Institute of Technology. At Tech, he was a member of the varsity swim team and graduated in 1972 with a major in Nuclear Physics and a minor in math. He also became fluent in Russian which proved useful later in his life.

Harry became a programmer at Delta Air Lines in Jan 1973. At Delta, he became an invaluable member of the ACP (now TPF) Operating Systems Group and also worked as an information services instructor for the company. In the early 80’s, Harry left Delta and went to work for Amdahl computers. He worked there until IBM recruited Harry from Amdahl in 1987 to IBM’s TPF group. Harry was so skilled that when things went wrong with a business customer’s reservation system, senior IT VP’s of major IBM customers would ask for Harry by name to trouble shoot their problems. He rose through the technical ladder at IBM to Senior Engineer/Programmer- TPF Field Support. He traveled around the country and the world as a TPF consultant and instructor for IBM.

In addition to the professional part of his life, Harry was a wonderful friend, brother, and partner; he was kind, thoughtful, and patient. He was a great listener and always willing to help. As a friend and advisor, Harry knew when the best course of action was to listen. He was beloved by his friends and highly respected. He had a personal wealth and breadth of knowledge. Before there was Wikipedia or Google, there was Harry. If you needed to know a date, a reason for a war, or why the Marathon was extended by 0.4 miles in the 1920 Olympics in London, Harry either knew the answer or knew where to quickly find it. He continued to be very active and was proud of the excellent physical condition he maintained. He ran in the first Peachtree 10k Road Race in Atlanta, GA held on July 4th over 30 years ago and has run in every Peachtree Road Race – either officially or unofficially.

A memorial service will be held at the O’Connor Mortuary 25301 Alicia Parkway, Laguna Hills, CA on Tuesday Oct 11, 2011 at 7:00 PM. Services will also be held at the Thomas McAfee Funeral Home in Greenville, South Carolina. Visitation and a Rosary Service will be held at 6:00 PM Friday Oct 14, with a Funeral Service at Noon on Saturday Oct 15, 2011.

In lieu of flowers the family requests donations to the Human Rights Campaign, 1640 Rhode Island Ave., NW, Washington, DC 20036-3278, Attention Mr. Joe Tapp (phone number 480-343-1333)

  1. Harry was the thing and not a copy of anyone else. His love for his Dad “Mac” during
    his last days is one of the most memorial and loving care I have ever seen.

  2. From the time I first met Harry in 1973 when he joined Delta until I last worked with him at IBM in 2008, we had a very good working relationship. All who came in contact with Harry for TPF support and education were very fortunate to have the exposure to his exceptional technical and business expertise. We will all miss Harry as he left us too soon. Bina’s and my thoughts and prayers go you, Edgar and Mark, and all of Harry’s extended family.

    I am very sad to hear about Harry’s sudden passing. I was very impressed with his knowledge of the TPF system, especially in data communications, the area of the system that he would ask me questions about. IBM will miss his outstanding customer support and his overall knowledge of the TPF sytem. I offer my condolences to his family.
