Kalman Laki (February 1, 1909 – February 12, 1983), sometimes referred to as Koloman Laki, was a Hungarian-American biochemist who contributed to the discovery of factor XIII. He was a scientist at the US National Institutes of Health (NIH).
Laki and biochemist Laszlo Lorand (whom Laki had recruited to Albert Szent-Györgyi's laboratory when Lorand was a medical student) worked on biochemical research in coagulation.[3] A substance they identified, initially named Laki–Lorand factor, became known as factor XIII.[4] Laki was awarded an honorary medical degree from the University of Debrecen.[2]
