Harold M. Frost (1921 – 19 June 2004) was an US-American orthopedist and surgeon considered to be one of the most important researchers and theorists in the field of bone biology and bone medicine of his time. He published nearly 500 peer-reviewed scientific and clinical articles and 16 Books and is according to the Science Citation Index one of the most cited investigators in skeletal research.
He received his medical degree from Geisel School of Medicine and Feinberg School of Medicine in 1945. He then did his surgical internship in Worcester, Massachusetts . During this time he was Officer in the Naval Medical Corps from 1946-1948. He then did his residency in Orthopedic Surgery in Buffalo General and Children's Hospital, NY from 1948 to 1953. In 1955, he became an Assistant Professor of Orthopedic Surgery at Yale School of Medicine . He eventually moved to Detroit at Henry Ford Hospital where he became the founder and Director of the Orthopedic Research Laboratory. He remained the director until 1973 and also took on the Chairman position of the department from 1966 until 1972. .
During his time at the Henry Ford Hospital, Dr. Frost made many breakthroughs, which changed the paradigm of bone biology.
Frost moved to Pueblo in 1973,— drawn by the mountains, climate and laid-back lifestyle — he brought with him his international reputation as a dogged researcher, talented orthopaedist and prolific author. While there he continued his active participation at the Sun Valley Workshops where he interacted with participants to develop cancellous bone histomorphomety (1977), generate and refine the mechanostat hypothesis (1987), and the ever-evolving Utah Paradigm of Bone Physiology (1997), and many, many more.
His main academic inputs included:
