Robert O. Becker was a U.S. orthopedic surgeon
Surgeon
In medicine, a surgeon is a specialist in surgery. Surgery is a broad category of invasive medical treatment that involves the cutting of a body, whether human or animal, for a specific reason such as the removal of diseased tissue or to repair a tear or breakage...

Electrophysiology
Electrophysiology is the study of the electrical properties of biological cells and tissues. It involves measurements of voltage change or electric current on a wide variety of scales from single ion channel proteins to whole organs like the heart...

His research

Having observed in his clinical practice that broken bones sometimes failed to grow together, he set out to study experimentally why, and if external physical conditions could improve the growth. He found that a DC
Direct current
Direct current is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also flow through...

 current through the broken bone (about 1 nanoampere) would greatly improve the growth and fusion of the bones. During this work, Becker found it significant that lower animals had much better regeneration
Regeneration (biology)
In biology, regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organs, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. At its most...

Salamander
Salamander is a common name of approximately 500 species of amphibians. They are typically characterized by a superficially lizard-like appearance, with their slender bodies, short noses, and long tails. All known fossils and extinct species fall under the order Caudata, while sometimes the extant...

s seemed to be a little too high on the evolutionary ladder to achieve this regeneration. He studied these animals for years in order to find out why evolution caused impaired regeneration capabilities, and whether electric field

In physics, an electric field surrounds electrically charged particles and time-varying magnetic fields. The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding...

Harold Saxton Burr
Harold Saxton Burr was E. K. Hunt Professor of Anatomy at Yale University School of Medicine. His early years were spent in Springfield, Massachusetts, while most of his later life was spent in New Haven. In 1908 he was admitted to the Sheffield Scientific School at Yale and received his Ph.B. in...

Field (physics)
In physics, a field is a physical quantity associated with each point of spacetime. A field can be classified as a scalar field, a vector field, a spinor field, or a tensor field according to whether the value of the field at each point is a scalar, a vector, a spinor or, more generally, a tensor,...
