Gregory Alan Schumacher

February 06, 1958 ‒ November 30, 2017

Sunbury, Ohio

Gregory A. Schumacher, 59, of Sunbury lost his four-year battle with brain cancer on Thursday afternoon, November 30, 2017 at the Ohio Living Sarah Moore Home surrounded by his loving family.

Greg worked 30 years as a geologist for the State of Ohio, Division of Geological Survey. His love and passion for geology started when he was a young boy and never waned. His other passions included his family, military history, do-it-yourself projects, and all living creatures, especially cats. He was a founding member of Spay and Neuter Abandoned Cats and Kittens, Inc., a nonprofit organization.

Left to cherish his memory is his loving wife of 30 years, Rita; son, Joseph Benjamin; his mother, Mary; brother, Mike (Candy) and several nieces and nephews.

Greg was preceded in death by his father, Tony.

Greg fought this terrible disease with courage, dignity, a positive spirit, and determination. The family would like to thank Greg’s neuro-oncologist, Dr. Mohamed Hamza and his staff, the Ohio Health Hospice care team, and Ohio Living Sarah Moore LTC 3rd floor, for their good care, kindness, and their compassion. We also thank our friends and family who offered support to Greg on this long journey.

Greg was cremated and his ashes will be buried at a later date.

Celebration of life services will be held on Tuesday, December 5, 2017 at 11:00 am at the Snyder Rodman Funeral Center, 101 Valleyside Drive (formerly 1510 W. William Street), Delaware. Following the services, friends and family are invited to spend additional time together celebrating Greg’s life enjoying a meal including some of his favorite foods – pizza, pie, and cookies in the Snyder Rodman Community Room.

In lieu of flowers, please consider a donation in Greg’s memory to Ohio Health Hospice, 180 E. Broad Street, Columbus, OH 43215 or your favorite animal welfare organization.

  • Rita and Ben,
    My heart is saddened for the loss of Greg. I was honored to have known/worked with a wonderful compassionate man for over 20 years. May God bless you and Greg.
    Love, Hallie

  • Few people have better embodied what it is to be a geologist than Greg. Greg was a noted authority on the Ordovician -aged rocks and yet he could explain and tell a story that could educate and captivate every audience. Greg’s influence at the Ohio Geological Survey was perhaps best exemplified by the pride and care he took organizing the HR Collins Core Repository at Alum Creek State Park. I cannot visit the lobby area and not picture Greg there explaining rocks and fossils to anyone in his presence.

  • Rita and Ben,

    We are so very, very sorry for your loss of Greg. We will remember him as a compassionate animal lover, an interesting conversationalist and a guy with a great sense of humor. Please know you have our deepest sympathies and that you are all in our prayers.

    Surrounding you in light and love,
    Gail & Bob

  • I had the honor of working with Greg at the Geological Survey for most of his 30-year career. I am awed at his achievements in researching and mapping the geology of Ohio. He was a fine, hardworking geologist who knew his craft and was graciously willing to share his knowledge. Greg was an esteemed colleague for which I am grateful to have known. We had so many great days in the field together.

    My best wishes for strength go out to Rita and Ben. I will miss Greg Schumacher.

  • When I moved to Ohio, I met Greg and Rita at an exercise class. They were so kind and welcoming, asking me to join them for coffee and conversation. Over the years I was privileged to continue the friendship. I will miss Greg’s compassion and his vision to make the world a better place. I was fortunate to know him.

  • I knew Greg as a friend and colleague from the early days of the bedrock mapping program at the Ohio Geological Survey. He was generous and kind with great personal integrity and a wry humor. Those few early years we worked together were a special time in my career. Greg is there among my fondest memories of the days when we were young field geologist.

  • I am honored to have worked with Greg in the last few years of his career at the Ohio Geological Survey, and especially grateful for spending time with him doing field work for his last—though one of the Survey’s most important—publications: Ohio’s Geology in Core and Outcrop. We had wonderful, often philosophical conversations about a great many things beyond geology while driving throughout western and southwestern Ohio. I was always impressed by Greg’s passion for his work and ability to tell the story of Ohio’s geologic history in a way that was easy to understand. My sincerest condolences to Rita, Ben, and the rest of the family.

  • Greg Schumacher was a wonderful man, an excellent geologist, and a friend. He taught me so much about the Geology of Ohio when I first came here early in my career. I enjoyed our time together during my annual visits, with my students in tow to the Geologic Survey. He will be sorely missed.

  • Greg Schumacher was a passionate and exacting geologist who served the people of this state with distinction at the Ohio Geological Survey for 30 years. Greg knew our science very well, and put his pen to maps and reports with perfection and high competence. He understood sedimentology, stratigraphy, paleontology, and glacial geology, and put those aspects of our science to work in preparing thorough and precise geologic maps for our citizens. Greg was a consummate field geologist, carrying himself across Ohio’s landscape with an eye for important data and amazement at the hand of the Creator. I will never forget the day Greg and Dennis Hull and I were trekking through some woods in southwest Ohio. Greg had brought us to an exposure of a huge meltwater deposit that just took our breath away. He exclaimed, “Will you look at that!”

    Greg Schumacher’s passions for precision and good organization were admirably applied to the Collins Core and Sample Repository at Alum Creek State Park. He made it an outstanding resource for people working on the geology of Ohio—especially the subsurface.

    I will certainly miss Greg. He fought the good fight in his illness. He worked tirelessly to bring good geology to the people of Ohio. I extend my heartfelt sympathy to Rita and Ben. We are all fortunate to have known Greg.

    May God bless Greg, and hold Rita and Ben in His loving arms,
    Thomas M. Berg, Emeritus Ohio State Geologist

  • I am honored to have known Greg throughout my career and to have worked with him at the Ohio Geological Survey for the last few years of his career at the Survey. He was an amazing geologist. His love and passion for the geology was apparent whenever we spoke.

    The nonprofit Spay and Neuter Abandoned Cats and Kittens is an amazing organization that has spayed/neutered thousands of cats. We used SNACK’s services for two of our cats who showed up as strays to our house. My wife Kit and I will continue to support their mission.

    It was a honor to have known Greg. He will be missed. Condolences to the family.

  • I am deeply saddened to learn of Greg’s passing, and I offer my condolences to the family. I had the pleasure of supervising Greg’s Masters Thesis at the University of Cincinnati. Greg is among my best-ever students and he contributed an excellent research thesis on crinoid paleoecology and taphonomy. He was truly dedicated to his work and a great student in all respects. I was so pleased he could work as a geologist with the Ohio State Geological Survey and to make so many fundamental contributions to geology and paleontology of the state. The position was the perfect job for him, I think, and he took to it with great energy and dedication. I hold Greg very dearly in my memory and am thankful to have been able to help him on the way to an illustrious career. His work stands as a lasting and significant contribution to our knowledge of Ohio’s rich geological heritage.

  • Although ,we only had the pleasure of knowing Greg through SNACK (Spay Neuter Abandoned Cats and Kittens) for a few short years, we learned a lot from him in that time. We will remember him for his compassion , strength and hard work towards a mission that many overlook, and a little laugh to go with it. May Rita and Ben always have joy in their hearts from the wonderful memories he has left with them.
    With all our love and sympathy, Nicolette and Cheryl
