Leonard Michael Sieradski Jr.

Leonard Michael Sieradski, Jr., 82, of Fort Wayne, Indiana passed into eternal life on June 15, 2020. Leonard was born to the late Leonard and Eleanore Sieradski on January 31, 1938 in Detroit, Michigan. He attended Marmion Military Academy in Aurora, Illinois and earned Bachelor of Science degrees in Mathematics and Physics at the University of Dayton, Ohio.  He earned his Master’s of Science degree in Physics from Purdue University.  A gifted scientist and inventor, Len began his aerospace/energy career at Bendix Research Laboratories where he developed the Time-of-Flight Mass Spectrometer for lunar exploration.  He was a senior scientist at Jet Propulsion Labs where he directed the design and development of the Magnetic Sector Mass Spectromenter used on the Viking Mars Lander Spacecraft.  Following this, Len started Sunrise Energy Products Corporation with his father and three brothers, designing and building innovative solar energy products. He also worked at Northrup Energy Corp., Mid-America Solar Energy Corp. and Talandic Research.  He finished his career at ITT Aerospace where he worked on NASA’s GOES satellite.  Len held several patents in three countries for his inventions.  In his later years he became interested in health and wellness and ran his own successful website business, Old Amish Dewormer.  Len was a Fourth Degree Knight of the Knights of Columbus Father Solanus Casey Council 11276 and a very active member of Saint Elizabeth Ann Seton Catholic Church.  Leonard is survived by the love of his life of 52 years, Floral Anne Sieradski, of Mildmay, Ontario, whose heart he charmed at a chance meeting and to whom he was endlessly devoted, as well as his four children; Diana, Michael, Libby, and Angela, their spouses, and his cherished grandchildren.  Perpetually curious, Len was a pioneering renaissance man, the go-to guy for every challenging problem or situation, and a magical “MacGyver” who could seemingly fix anything.  He was quick with the harmonica or a Dad joke, quietly romantic and sentimental, and known to drop everything to help others in need.  Mass of Christian Burial will be at Saint Elizabeth Ann Seton Parish, 10700 Aboite Center Rd. Ft. Wayne at 10:30am with calling 1 hour prior. This service can be viewed  at www.seasfw.org/ for those unable to attend in person. Visitation will be held Wednesday, June 24, 2020, 4:00 pm - 7:00 pm with a rosary at 4:30pm at Divine Mercy Funeral Home, 3500 Lake Ave., Fort Wayne.  Face masks will be required.
