Alexander Thomas Hennesy passed away peacefully on November 18, 2025, in Saint Charles, Missouri, at the age of 74. Born on December 17, 1950, in Hanover, New Hampshire, to the late Willard Dean and Anna Dorothy Hennesy, Alexander lived a life defined by dedication to his family and his work.

Alexander enjoyed a long and distinguished career with The Boeing Company. His professional journey took him from Seattle, Washington, to Saint Charles, Missouri, where he eventually retired. Following his retirement, Alexander fulfilled a lifelong dream of traveling the country in an RV with his wife, exploring the open road for several years. Ultimately, they returned to settle in the home he was most proud of, where he found great joy in maintaining his yard and spending time in his sanctuary.

He will be remembered as a devoted husband, a loving father, and a selfless caregiver who always put the needs of others before his own.

Alexander is survived by his beloved wife of 52 years, Ruth Ann Hennesy (née Staton); his daughter, Mary Jean Hennesy; and his son, Alex Patrick Hennesy.
