This special article describes the achievements and impact of Dr. Todd Siu‐Toa Ing, MBBS, (1933–2023) on the field of nephrology as recounted by a colleague from Hong Kong, a U.S. nephrologist ex‐trainee, and the daughter of an important mentor. Dr. Ing was a founding member of the International Society for Hemodialysis. He made important discoveries regarding the diagnosis of renal tubular acidosis and electrolyte transport in the gastrointestinal tract and published many innovative findings relating to peritoneal and hemodialysis. He was especially interested in nephrology and dialysis education and was co‐editor of a Handbook of Dialysis that has been in publication in five editions since 1988 with translation into many foreign languages. Dr. Ing was very supportive of nephrology in China as well as Chinese nephrologists practicing in the United States, and was a founding member of the Chinese American Society of Nephrology.
