Born on February 5, 1951 in Chambon-Feugerolles, France, he was the son of Gracjan and Jeanine (Knapik) Motowidlo of New Britain. He and his family immigrated to the United States in 1955.
A much-honored physicist, Leszek began his prodigious journey in applied physics with studies at Central Connecticut State University. He then went on to the University of Connecticut and received his M.S. in Physics in 1976 and his Ph.D. in Metallurgy in 1981 under the supervision of Dr. James Galligan.
Thereafter, Leszek joined Varian Associates and served as Visiting Scientist at MIT. He returned to Connecticut in 1986 to work at Intermagnetics General Corporation as a manager and group leader. A proud Husky, Leszek received the distinguished Alumni Award from the UCONN School of Engineering in 1996 for his outstanding contributions to both the science and engineering applications of superconducting materials. His work was well-received nationally and globally; he had presented numerous invited papers at conferences on high-temperature and low-temperature superconductors around the world.
But Leszek’s most impressive accomplishments shone right here in Connecticut. Until his death, he was owner and president of SupraMagnetics, Inc. in Plantsville, a research and development company he started in 2004. Leszek was also a fierce competitor, swimming at CCSU during his collegiate days and participating in several triathlons and road races in his life. He also loved the outdoors and sharing a good glass of Cabernet Sauvignon with family and friends.
Leszek would attest, however, his proudest accomplishments were the relationships he built, his family and friends. In addition to his wife and parents, he leaves behind his children Adam Motowidlo of Hartford and Cara Motowidlo of New York City, a sister Danielle Motowidlo of Torrington, and a sister-in-law Susan Dorsey of Plantsville. He was predeceased by a brother-in-law John Dorsey, Jr.
He was also much beloved by his niece and nephew, Jocelyn (Morante) LaRocca and Daniel Morante, along with his brother-in-law Charles Morante. Finally, he leaves behind his treasured beagle and littlest love, Shyatsu.
His funeral will be held on Monday at 10:15 a.m. from the DellaVecchia Funeral Home, 211 N. Main St., Southington to Mary Our Queen Church, 248 Savage St., Plantsville.
