James Mangus Obituary

James D. Mangus, a brilliant engineer known for his exceptional contributions to the field of nuclear reactor design, passed away peacefully on February 7, 2024, at the age of 89. He devoted his life to the pursuit of knowledge, serving as a shining example of perseverance and intellectual curiosity.

James, born on November 4, 1934, in Indianapolis, IN, was the beloved son of the late Norman Mangus and Mary Cox. He completed his bachelor's degree in engineering from Purdue University where he met the love of his life and wife of 58 years, Pat. Following his academic pursuits, James served in the United States Air Force before commencing an illustrious engineering career with Westinghouse. Driven by his ingenuity and a knack for innovation, he developed multiple patents in nuclear reactor technology.

Travel played a significant role in James' life. His work took him to destinations as diverse as France, Japan, and England, where he immersed himself in unfamiliar cultures and forged enduring bonds. Yet, amidst his global adventures, it was Hawaii that held a cherished corner of his heart, a place he frequented with his beloved Pat.

Beyond his professional achievements, James had passion for continuous learning. His thirst for knowledge led him to study various religions and delve into history and science. James found joy in channeling his creativity through watercolor painting, and his love for the arts extended to the ballet, musicals, and symphony performances alike. Seldom seen without a cup of coffee at hand, he would occasionally reveal his discerning taste for a glass of merlot or single-malt scotch whisky, a testament to his refined palate.

Family was paramount for James, and he deeply cherished every moment spent with his children, grandchildren, and great-grandchildren.

James was preceded in death by wife Patricia Kelley Mangus, children Cyndi (Kenny) Mangus-Veach, and Chris Mangus.

James was survived by children Cheryl (Bryan – deceased) Mangus Speicher, Don Mangus; grandchildren Kelley (Cary) Speicher Aronson, David (Brittany) Speicher, and Sean Mangus; great-grandchildren Zane, Nat, Quinn, and Asher; sisters Kathi Kelley and Judy (Barry – deceased) Kelley; also, numerous nieces and nephews.

A man of many talents, James leaves behind a legacy defined by his relentless quest for knowledge and dedication to his profession. He will be fondly remembered for his sharp wit, unending kindness, and his ever-present smile.
