Marcus Edward Kellerman

Aug 17, 1939 - Aug 3, 2025

Sandusky

Marcus Edward Kellerman was born August 17, 1939, in Sandusky, and passed away August 3, 2025, at Stein Hospice Care Center, Sandusky, a couple weeks short of his 86th birthday.

His parents, Marcus and Mary (Parker) Kellerman, raised him a youngster above the family's grocery store at the corner of Camp and Osborne streets, from where he began his schooling at Holy Angels Elementary School. He eventually completed his high school education at St. Mary's High School, graduating in 1957, then left for the University of Detroit where he earned his Electrical Engineering degree. Later, he earned his Masters Degree in Business in El Paso, TX.

Mark learned how to work at an early age, performing odd jobs around the family's grocery business, Mark's Market, and later Mark's Pic-n-Pay. Since retail did not interest him, he began another career working at governmental facilities such as Oak Ridge Tennessee, then with the newly founded NASA at the Plum Brook facility where he helped test the Saturn engine that put a man on the moon. Later, he found his true vocation: working with IBM in their computers' early days, as business and government needed machines installed and made operational. He began that career in El Paso, bounced back to Washington D.C., then back out to Los Alamos, NM. Along the way, he married, and the couple finally settled in Santa Fe, NM. After retiring, Mark taught business courses at a northern New Mexico college. After 51 years of marriage, Mark's wife Carol passed, and he moved back to his roots in Sandusky.

Mark and Carol traveled the world, exploring cultures on every continent except Antarctica, the major islands in all the oceans, and many of the tallest mountains where they loved to ski. At home, Mark belonged to the Santa Fe Model Railroad Club and filled his property's three-stall horse barn with a train layout, with the HO's traversing every miniature region of the USA. With Santa Fe being an art capital of the West, the couple patronized all the arts, both in the Santa Fe area and many museums and opera houses around the world. For years, being an accomplished musician, Mark was also the organist at his church.

Mark and Carol's "children" were the many rescue cats and dogs they housed over their 51 years of marriage. The couple's Great Pyrenees especially miss their devoted masters.

Preceding Mark in death were his wife, Carol, who fought Parkinson's for 20 years; parents, Mark and Mary Kellerman; sister, Dolores Mary Heydinger and her infant son, Joseph; and numerous South Bass Island Parker aunts and uncles, cousins, and friends. On Carol's side of the family, Mark was preceded in death by Carol's siblings, Mary Bittner (Robert), James, and Joseph (Wanda); and by their niece, Karen Bittner.

Surviving Mark and Carol are his brother-in-law, Michael Heydinger of Sandusky; nephews, Scott of Lexington, KY, Marcus of Sandusky, and Charles (Vicky) of Savannah, GA; great-niece, Taliesin Heydinger of Savannah, GA; South Bass Island aunt, Ann Parker; and numerous cousins and friends. Surviving on Carol's side are Kristi Bittner (Mimi), James Jr. (Carol), Jerome (Cheryl), JeanAnn, John (Monica), and Jack (Kelley), Sue Woodward (Ken), and Michael, and numerous grand- and great-grandnephews and nieces.

Those wishing to honor the memory of Mark and Carol Kellerman may make a contribution to their nearest animal shelter or Stein Hospice Service, Inc., 1200 Sycamore Line, Sandusky, Ohio, 44870.

There will be no local Sandusky visitation nor services, but a Zoom service will take place at a later date from Santa Fe, NM, and the cremains of both will be placed in their church's rose garden.

Arrangements have been entrusted to David F. Koch Funeral and Cremation Services, 520 Columbus Avenue, Sandusky.
