Robert Frederick Frobenius II (“Bob”) was born June 5, 1945, in Denver, Colorado and passed away on February 4, 2026, in Salina, Kansas.

Bob is survived by his beloved wife, Diana Frobenius (née Sapp); his sons, Robert Frobenius III (Stacie) and Anton Frobenius (April); and his grandchildren, Ethan Frobenius and Elliot Frobenius. He was preceded in death by his parents, Alta Frobenius (née Swisher) and Robert Frederick Frobenius, Sr., and by his brother, James Frobenius. Bob devoted much of his life to service and the care of others. He served as a deputy with the

Saline County Sheriff’s Office, later as an officer with the Derby Police Department, and also worked in security with Boeing. In time, Bob became a funeral director and the owner of Roselawn Mortuary and Roselawn Memorial Park Cemetery, a calling he carried with dignity and compassion. Bob had a spark—opinionated, candid, and full of emotion. He could be difficult at times, but it was never from indifference. He lived with his heart on his sleeve, loved fiercely, and remained deeply family oriented. Even through difficult later years, he kept a zest for life and a drive to learn, always reaching for understanding and knowledge. Bob loved working with people, time in nature, and learning for learning’s sake. He had a deep interest in genealogy and spent countless hours researching the background of his family tree. He traveled extensively, including through humanitarian interests, and remained curious about people’s stories and the wider world. He also enjoyed shooting sports and the discipline and focus they require.
