Leonard Charles Wooldridge MB BSc DSc MD (Dec 1857 - 6 Jun 1889) was an English physician and physiologist.

His pioneering work on tissue fibrinogens provided new insights into thrombosis, cirrhosis, and immunity, influencing the field of experimental medicine.

[1] During his studies, he demonstrated exceptional academic ability, earning multiple distinctions and prizes in examinations for degrees including MB BSc DSc and MD.

His work on the chemical composition of blood cells led him to observe coagulation phenomena that could not be easily explained by existing scientific theories.

[1] In 1881, Wooldridge was awarded the George Henry Lewes travel scholarship by Professor Michael Foster, which enabled him to study pathology under Rudolf Virchow in Berlin during the winter of 1883.

His dedication to research led him to spend long hours in the hospital and laboratory, frequently foregoing rest and proper meals.

[1] In the spring of 1889, during a period of extreme overwork, Wooldridge fell ill after eating a late lunch at Guy's Hospital, which he suspected contained spoiled fish.

[4][1] Wooldridge's contributions to the understanding of blood coagulation, thrombosis, and immunology left a lasting impact on the medical community.
