Miles Harold Letts II passed away peacefully on Sunday, July 11, 2026, a week shy of his 95th birthday. He is remembered as a beloved father, Papi, brother, uncle, cousin, husband, loyal and cherished friend, civic leader, business executive, inventor and creator, outside the box thinker, musician, expert joke teller, boat captain and adventure leader.

Miles was born and raised in Owosso, Michigan and was a graduate of Michigan State University with an undergraduate degree in Computer Science and a Master's in Information Systems. After graduating, Miles' service as a Captain in the United States Air Force brought him to the Washington DC area, his home for the majority of his remaining years. He completed his Air Force service at the Pentagon, where he was able to develop his lifelong love of cutting edge technology.

Following his time in the military and Pentagon, Miles fueled our nation's small business economy when he went on to co-found and eventually lead System Sciences, a software company based in Bethesda, MD that, among many other things, collected and processed data and information to care for our country's veterans in partnership with the Veterans Administration. In parallel, Miles founded and was CEO of Trak Tech Corporation, where he developed railroad track safety testing software and hardware, whose primary objective was to protect and keep safe our nation's Eastern seaboard railroad tracks in partnership with Amtrak. Trak Tech also protected and kept safe Washington DC's Metro (subway) system in partnership with the Washington Metropolitan Area Transit Authority. As CEO of both companies over the years, Miles was responsible for the livelihood of over a hundred employees and their families.

Miles was a devoted family man who loved spending time with family and cherished friends and he was always creating opportunities to bring his loves together. He was so committed to his family unit that he lovingly adopted his second wife's adult children, Rana and Marc.

One of Miles' life reel highlights was his boat, Miles to Go, where he joyously and patiently taught his children (and their friends) to water ski, water tube, fish like pros, crab like locals and navigate the waterways of the Chesapeake (and Occoquan and Potomac). An adventurous spirit, Miles traveled to all seven continents, sometimes in service of his Rotary Club (where he participated and served in leadership positions, for almost 30 years) helping promote small business and sometimes visiting his far flung family. Later in his life, Miles added RV (recreational vehicle) travel to his adventures. His favorite place to be was Blue Haven, the house he built on Drum Point in St Michaels, MD.

A brilliant man never burdened by conventional thinking, Miles was always tinkering with something, either making it better than it was or creating something from scratch that solved a problem. His inventions and creations were legendary and much loved by his family and friends alike. If something was broken, Miles got the call. If technical advice was needed, Miles was first in line. If there was a new technology available, Miles was an early adopter. He had a cell phone in the 80s when they were carried around like briefcases. And later in life, he enjoyed having conversations about big machines, quantum computing and AI, staying on top of all the latest developments, even at their rapid fire pace. One of his life reel highlight creations was his 1920s Mercedes kit car which he built and loved driving, especially in less crowded St. Michaels. HIs technical savvy and impact was lifelong.

Miles' sense of humor was one of his leading qualities, along with his ability to tell a colorful story. He was always good for a "dad" joke and all you had to do was laugh once and he happily doled out an endless supply of jokes for any captive audience. His stories were filled with immense detail and fantastic learnings, color and little fiction - but perennially entertaining! He was a jovial man whose laughter echoed throughout and his presence was always felt in a positive way wherever he found himself.

Miles was a man of deep faith and would inevitably have a conversation with you about your relationship with God. He was deeply grounded in his faith, unwaveringly so, and spent a lot of time and energy ensuring that if you remembered nothing else from a conversation, you knew that a life is not complete without a solid foundation in faith and a deeply entrenched relationship with God.

With such an active and brilliant mind, Miles was always reading or learning something. He would often challenge perceptions and perspectives solely for the purpose of encouraging and considering different points of view. He had so many hobbies, including technology, music, games that challenged him such as bridge and chess, astronomy, and was constantly adding new hobbies as they piqued interests in his ever active mind.

An avid musician, Miles could often be found behind a keyboard playing, teaching others to play or simply enjoying the beautiful sounds the keys created. In his earlier years he was an enthusiastic horn player and one of his most prized and coveted possessions was the clarinet he was gifted by the late Tommy Newsome, the former band director of the Tonight Show with Johnny Carson.

Miles' favorite role of his life was being Papi. He loved his grandchildren immeasurably and thoroughly enjoyed all stages of their lives. From the minute they were born, he was their biggest fan and advocate, doling out advice and life lessons from the get go. When he read to them, he did all the voices. He watched every Disney movie (many times!) and all the Mickey Mouse Clubhouse and Bob the Builder episodes. He never missed a school function, birthday party, little league baseball, basketball or other sporting event and loved going on vacation with his grandchildren, checking all the Disney and amusement park boxes with glee. Papi provided financial advice as they got older, helped with homework and other fun things they brought him to ponder, ruminate on or participate in. His Papi highlights included playing the part of Monet daily at their elementary school for "Monet Week" (still talked about by the staff with admiration and delight 15 years later), helping his namesake build a computer from parts, showing off his Alexa (AI) run household system to turn on lights, start the coffee machine and run devices at his home to his grandsons who were in complete awe of his endless, amazing technical skills, making pizza together, playing rousing games of chess, endless games of Candyland, Monopoly, Wii and later video games. His appetite for love was insatiable and his favorite place to realize it was with his grandchildren.

He is predeceased by his parents, Miles and Margaret, his infant son Franklin and infant daughter Robyn. Miles is survived by his three remaining children, Debbie, Rana (Kevin) and Marc (Jessica), his grandchildren Aidan, Ethan, TJ, Luke and Emily and two great grandchildren, his brother, Dr. Neil Letts and numerous nieces and nephews around the world, many of whom referred to him as Uncle 1.6 Kilometers.
