Sir Thomas Lewis CBE FRS FRCP (26 December 1881 – 17 March 1945) was a Welsh cardiologist. He coined the term "clinical science" and is also known for the Lewis P Factor.

Early life and education

Lewis was born in Taffs Well, Cardiff, Wales, the son of Henry Lewis, a mining engineer, and his wife Catherine Hannah (née Davies). He was educated at home by his mother, apart from a year at Clifton College, which he left due to ill-health, and the final two years by a tutor. Already planning to become a doctor, at the age of sixteen he began a Bachelor of Science (BSc) course at University College, Cardiff, graduating three years later with first class honours. In 1902 he entered University College Hospital (UCH) in London to train as a doctor, graduating MBBS with the gold medal in 1905. The same year he was awarded a Doctor of Science (DSc) degree from the University of Wales for his research work.

Career

Lewis remained at UCH for the rest of his life, beginning as a house physician. From 1907 he also worked at the Royal Naval Hospital, Greenwich and the City of London Hospital and the same year he took his Doctor of Medicine (MD) degree. In 1911 he was appointed lecturer in cardiac pathology at UCH and in 1913 was promoted to assistant physician in clinical work. He was elected Fellow of the Royal College of Physicians (FRCP) in 1913.

While still a house physician, Lewis began physiological research, carrying out fundamental research on the heart, the pulse and blood pressure. From 1906, he corresponded with the Dutch physiologist Willem Einthoven concerning the latter's invention of the string galvanometer and electrocardiography, and Lewis pioneered its use in clinical settings. Accordingly, Lewis is considered the "father of clinical cardiac electrophysiology". The first use of electrocardiography in clinical medicine was in 1908. In that year, Thomas Lewis and Arthur MacNalty (later the Chief Medical Officer of the United Kingdom) employed electrocardiography to diagnose heart block. In 1909, with James MacKenzie, Lewis founded the journal Heart: A Journal for the Study of the Circulation, which he renamed Clinical Science in 1933. In 1913, he published the book Clinical Electrocardiography, the first treaty on electrocardiography. Lewis was elected a Fellow of the Royal Society (FRS) in 1918. He was promoted to full physician at UCH in 1919.

During the First World War, Lewis worked at the Military Heart Hospital in Hampstead and was appointed as Director of the Medical Research Committee (MRC, later Medical Research Council) Department of Clinical Science at UCH, which was the first MRC Research Unit established in Britain. He directed a study of the condition known as "soldier's heart" and, having established it was not a cardiological problem, renamed it the "effort syndrome". In 1918 he wrote the monograph The Soldier's Heart and the Effort Syndrome. He devised remedial exercises that allowed many soldiers suffering from the condition to return to duty and was appointed honorary consulting physician to the Ministry of Pensions in April 1919, and for this work he was appointed Commander of the Order of the British Empire (CBE) in January 1920 and was knighted in the 1921 Birthday Honours.

After the war, Lewis established the clinical research department at UCH and continued his work on cardiac arrhythmia. In 1925 he switched his focus from cardiography to vascular reactions of the skin. In 1917 he had shown that capillaries had independent contractions and he now investigated the response of the skin to injury, leading to the 1927 monograph The Blood Vessels of the Human Skin and their Responses. He was awarded the Royal Society's Royal Medal in 1927 "for his researches on the vascular system, following upon his earlier work on the mammalian heart-beat." Next, he switched his focus to peripheral vascular disease, especially Raynaud's disease, and finally to the mechanism of pain, summarising his findings in Pain in 1942. His 1932 book Diseases of the Heart became a standard medical text. In 1930 he described the Hunting reaction, alternating vasodilation and vasoconstriction of peripheral capillaries in cold environments.

In 1930, he founded the Medical Research Society. He was awarded the Royal Society's Copley Medal in 1941 "for his clinical and experimental investigations upon the mammalian heart." He was only the second clinician to receive it, after Lord Lister in 1902. He served as vice-president of the Royal Society from 1943 to 1945.

Lewis suffered a myocardial infarction at the age of 45 and gave up his 70-cigarette-a-day habit, being one of the first to realise that smoking damaged the blood vessels. He died from coronary heart disease at his home at Loudwater, Hertfordshire, on 17 March 1945, at age 63.

Family

Lewis married Alice Lorna Treharne James in 1916. They had three children.
