Louis Napolean Pinsonneault

And He will raise you up on eagle's wings; Bear you on the breath of dawn; Make you to shine like the sun; And hold you in the palm of His hand

Louis Pinsonneault, 89, of Tucson, AZ, passed away on November 21, 2025, after a heroic battle with cancer. Born on August 8, 1936, to Napoleon (Nap) and Marie Pinsonneault in Crookston, MN, Louis lived a life filled with dedication and service.

After graduating from Lafayette High School in Red Lake Falls, MN, in 1955, Louis joined the United States Air Force, where he began a long and distinguished career in Electronics and Radar systems. On August 1, 1956, he married his high school sweetheart, Patricia (DuPont). Together, they welcomed two children, Cindy and Jeff, and spent many joyful years traveling the world during his 22 years of military service, culminating in his retirement as a Master Sergeant in 1977.

Following his service, Louis utilized the GI Bill to pursue a degree in Business at the University of Arizona, graduating in 1979. He then embarked on a 19-year career as an Accountant for TEP, retiring in 1998.

Louis was known as a quiet, gentle soul who cherished life, family, and friends. He loved to travel, enjoyed a good drink, and always knew how to have a good time. He was also known to play a mean game of cribbage.

He was predeceased by his parents, Napoleon and Marie, sister Carol Mickelson, and brother Paul Pinsonneault. Louis is survived by his beloved wife Patricia (Pat), daughter Cindy DeRousse (Tom), son Jeffrey Pinsonneault (Rose), grandchildren Jon, Sharie, Ashley, Samantha, Brittany, and six great-grandchildren: Rae, Ethan, Alicia, Owen, Corbin, and Hudson.

In loving memory of Louis, we celebrate a life well-lived and a spirit that will forever remain in our hearts.
