In Memoriam

Edward Bottei, MD, FCCP, FACMT
Our beloved friend, colleague and Iowa Poison Control Center Medical Director of 20 years passed away on April 27, 2022.  Dr. Edward Bottei, known simply as “Ed,” was a brilliant man—quadruple-boarded physician-scientist and master clinician. This extraordinary teacher, mentor and dear friend was also well known for his limitless kindness and generosity. Ed’s significant contributions to medical toxicology, the State of Iowa, and the Iowa Poison Control Center demonstrate the passion and dedication that he had for the field of toxicology and his work. He published numerous research studies and served on several statewide and national committees and advisory boards. He developed a fun and engaging jeopardy-style game for Specialists in Poison Information (“SPI Jeopardy”), which became a popular annual session for SPIs at the North American Congress of Clinical Toxicology. Beyond his many accomplishments and achievements, Dr. Bottei was greatly loved and respected by his colleagues throughout the poison center communities, his hundreds of students, and his IPCC family. His loss is deeply felt by all those who had the honor to know him. Always in our hearts. You will never be forgotten. Rest in Peace.
