May 10 2019:   On her 131st birth anniversary, Google worldwide, has carried a search page doodle remembering Lucy Wills, leading English haematologist who conducted seminal work in India in the late 1920s and early 1930s on macrocytic anaemia of pregnancy.
Her observations led to her discovery of a nutritional factor in yeast which both prevents and cures this disorder. Macrocytic anaemia is characterised by enlarged red blood cells and is life-threatening. Poor pregnant women in the tropics with inadequate diets are particularly susceptible. The nutritional factor identified by Lucy Wills (the ‘Wills Factor’) was subsequently shown to be folate, the naturally occurring form of folic acid.  ( photo and biographical details: courtesy Wikipedia
