William Alvin Moore Jr.

Al Moore, husband, father, grandfather and entrepreneur, passed away at the age of 90 on Oct 27, 2025.

William Alvin (Al) Moore, Jr. was born on May 14, 1935, in Jackson, MS to Eloise and William Moore. In 1940, at the age of 5, Al’s father passed away and along with his brother, James Love Moore, they were raised in a single parent home. The father figure in Al’s childhood was the Boy Scouts where he earned the rank of Eagle Scout and was introduced to rifle target shooting. Throughout his adolescence, college and early adult years, Al regularly competed at long range shooting competitions and in 1960, as a 25-year-old, he set a national rifle record.

Al received his mechanical engineering degree from Mississippi State University in 1957. After college, he moved to Fort Worth, TX and began his career as an Aerothermodynamics Engineer with General Dynamics. Al met the love of his life, Glenna, on a blind date and they married on June 12, 1962, in Big Spring, TX. Together, they raised four children: Lana, Trip, Marty and John.

In 1972, Al founded Tech Plan to sell air conditioning equipment to cool mainframe computers. This was a risky entrepreneurial venture for Al to undertake with the growing responsibility of providing for his wife and family. Fortunately, his business rode the emerging technology wave and by the 1980s, Tech Plan became the leading provider for thermal and power needs of computer rooms and data centers throughout North Texas.

Al and Glenna welcomed their first child, Lana, in 1963. Trip followed in 1965. And the twins, Marty and John, arrived in 1970. The Moore family moved to Dallas, TX in 1969 and put down lasting roots.

When not busy being a father and entrepreneur, Al, along with Glenna, enjoyed the friendships and competition from playing tennis at T Bar M Tennis Club. The family took many memorable vacations from road tripping throughout Texas, cruises to the Bahamas, ski trips to Lake Tahoe, river rafting excursions and beach vacations to South Padre Island.

By the time their kids had grown and moved away, Al and Glenna became the dating couple they used to be and set forth to live and love till eternity. As a couple, they traveled the world enjoying the adventures of barging down the canals of France, cruising through the Straits of Magellan, and ballooning over Switzerland.

Unfortunately, their worldly travels stopped when Glenna was diagnosed with ALS. As the disease progressed, Glenna’s body became weaker, and their unfailing love was clear as Al took care of his ailing wife until her passing on July 27, 2007.

Al endured two more untimely deaths in life when both his daughters passed away early, Lana in 2011 at the age of 47 and Marty in 2020 at the age of 50. And his brother, Jim, passed away on August 2, 2025.

Al leaves behind his son John, his son Trip and daughter-in-law Jackie, and two grandchildren, Blair and Hannah.

A Funeral Service to honor Al's life will be held at 10:00 a.m. on Wednesday, November 5, in the Chapel of Sparkman/Hillcrest Funeral Home, 7405 W. Northwest Highway, Dallas, TX 75225.

Memorials can be made in Al’s name to the Retina Foundation of the Southwest (www.RetinaFoundation.org/donate).
