by J. W. H. (John William Henry) Eyre
Born in London on July 18, 1869, J. W. H. Eyre built his career at the meeting point of laboratory science and medicine. He became known as a bacteriologist and ophthalmologist, with a special interest in infections of the eye.
He is best remembered by many readers today for The Elements of Bacteriological Technique, a clear, hands-on guide for students in medicine, dentistry, and technical fields. The book reflects his practical approach: careful observation, sound laboratory methods, and an emphasis on teaching usable skills.
Eyre remained active in British medical science into the early 20th century and died on February 17, 1944. Though not a household name now, his writing preserves the voice of a teacher-scientist working at a time when bacteriology was becoming essential to modern medicine.
