Before WWII, biological engineering had begun being recognized as a branch of engineering and was a new concept to people. Post-WWII, it grew more rapidly, and the term "bioengineering" was coined by British scientist and broadcaster
Heinz Wolff in 1954 at the
National Institute for Medical Research
The National Institute for Medical Research (NIMR), was a medical research institute based in Mill Hill, on the outskirts of north London, England. It was funded by the Medical Research Council (MRC);

. This was the first time Bioengineering was recognized as its own branch at a university. The early focus of this discipline was electrical engineering due to the work with medical devices and machinery during this time.
When engineers and life scientists started working together, they recognized that the engineers did not know enough about the actual biology behind their work. To resolve this problem, engineers who wanted to get into biological engineering devoted more time to studying the processes of biology, psychology, and medicine.
More recently, the term biological engineering has been applied to environmental modifications such as surface
soil protection,
slope stabilization, watercourse and shoreline protection,
windbreaks, vegetation barriers including
noise barriers and visual screens, and the ecological enhancement of an area. Because other engineering disciplines also address
living organisms
An organism is any living thing that functions as an individual. Such a definition raises more problems than it solves, not least because the concept of an individual is also difficult. Many criteria, few of them widely accepted, have been pro ...
