Reinhardt was the first physician to advocate
open-air treatment in England.[1] He established the Hailey Open-Air Sanatorium at
Ipsden,
Wallingford and acted as visiting physician.[2][3] The sanatorium contained a number of sleeping
chalets.[3] He was Honorary Secretary of the Open-Air League and co-authored a handbook on open air treatment.[4][5][6] In his book Diet and the Maximum Duration of Life, Reinhardt argued that
colon cleansing was responsible for postponing old age.[7][8] Reinhardt was influenced by the research of
Élie Metchnikoff and was one of the earliest physicians to promote the consumption of
yoghurt.[9] In his book 120 Years of Life: The Book of the Sour Milk Treatment (1910), he described yogurt as the "deliberate employment of microbes which confer a benefit upon their human host."[9]
He changed his second name to Reinhardt-Rutland in August 1914.[10]
Animal welfare
Reinhardt was an anti-vivisectionist.[8] He was associated with the
National Anti-Vivisection Society.[11] He served as Chairman for the
Council of Justice to Animals[12] and was an executive committee member for the Horses and Drivers' Aid Committee. In 1912, Reinhardt attended a meeting at
Torre Abbey in which he defended animals as akin to humans because they feel pain and experience suffering.[13] Reinhardt opposed excessive meat eating but promoted dairy products.[7]
