The office was created in 1976, replacing the previous office of Cook County Coroner.

Formation	April 1831
Final holder	Andrew J. Toman

The Cook County Coroner was the coroner of Cook County, Illinois until the position was abolished in 1976. The office of existed as an elected position from the early history of Cook County's government until its abolition in 1976.

The first Coroner of Cook County was John Kinzie Clark, who was appointed in April 1831.^[1] The first elected coroner, Orsemus Morrison,^[2] assumed office in 1836.^[3]

From the inception, the coroner's office was a department riddled with patronage and corruption. Ernst Schmidt, elected in 1862, resigned due to protest of interference with his job in January 1864.^[4] In its later years, occupants of the office and their inquest jurors often acted a rubber-stamp to the findings of the police and prosecutors.^[3]

In 1972, Cook County voters strongly voted by referendum in favor of eliminating the elected position of county coroner, replacing it with an appointed medical examiner.^[5][6] Several notable incidents which took place in the 1960s spurred this ^[3] This was the last time that voters in Cook County would vote on whether to eliminate an office until 2016, when they voted to eliminate the office of Cook County Recorder of Deeds and merge its duties into the Cook County Clerk's office.^[5] The office was eliminated on December 6, 1976.^[6] It was replaced by the appointed position of Cook County Medical Examiner.^[6]
