Quote of the Day: Hippocrates
Walking is man’s best medicine.
Hippocrates
Regarded as the father of Medicine (c.460-377 BC), gave his name to (though not sole author of ) the Hippocratic oath
Extracts of the Oath:
I swear by Apollo the Healer, by Asclepius, by Hygieia, by Panacea, and by all the gods and goddesses, making them my witnesses, that I will carry out, according to my ability and judgment, this oath and this indenture.
To hold my teacher in this art equal to my own parents …
I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrong-doing. …
Into whatsoever houses I enter, I will enter to help the sick, and I will abstain from all intentional wrong-doing and harm, especially from abusing the bodies of man or woman, bond or free. And whatsoever I shall see or hear in the course of my profession, as well as outside my profession in my intercourse with men, if it be what should not be published abroad, I will never divulge, holding such things to be holy secrets.

The blue plaque tribute to Dr Hannah Billig of London’s East End
(Why are there no images of Hannah Billig online? Do you have one?)

This may be Dr Hannah Billig but I’m not 100% sure
Update 28/1/19:
A friend of mine, a specialist in East End history, sent me these photos of Hannah Billig.
