Works & Achievements
His most famous conclusion: lacking any medical explanation for the girls' fits, he declared them bewitched, setting off the Salem witch trials.
He was one of the few physicians in the village, treating the population without a university degree, according to the methods of his day.
His niece and servant, who lived in his household, became one of the leading accusers, binding his home intimately to the crisis.
His name and his verdict appear in the accounts of contemporaries (Calef, Hale), the only lasting trace of his historical role.
Anecdotes
In January 1692, called to the bedside of Betty Parris and Abigail Williams, who were suffering from convulsions and strange screaming fits, Doctor Griggs could find no physical cause. His verdict came down: the girls were under the grip of an “Evil Hand.” That phrase lit the fuse and set off the Salem trials.
In Griggs's day, a colonial physician often held no university degree: he learned on the job, by assisting an older practitioner. When his knowledge fell short of explaining an illness, he might—like many others—turn to a supernatural explanation.
Elizabeth Hubbard, Griggs's own niece (and servant), who lived under his roof, became one of the most active accusers in Salem. She “testified” against dozens of people, placing the doctor's household at the very heart of the crisis.
A diagnosis of witchcraft was nothing absurd to the Puritans of the 17th century: they firmly believed that the Devil acted in the real world. The word of a respected physician was enough to turn an unexplained medical crisis into an accusation of a capital crime.
No work, diary, or portrait of William Griggs has come down to us. We know him only through the Salem court records: a man who, with a single consultation, unwittingly helped bring about the deaths of twenty people.
Primary Sources
The local physician, named Griggs, having visited the afflicted girls and finding nothing natural to explain their condition, gave it as his opinion that they were under an Evil Hand.
These children were afflicted with pains and movements so strange that they could not be attributed to any ordinary illness; the physicians consulted concluded that they were bewitched.
Elizabeth Hubbard, aged about seventeen, living in the service of Doctor William Griggs, testifies that she was tormented by the specter of the accused.
Key Places
The rural Massachusetts town where Griggs practiced and where the witchcraft crisis began in 1692.
The minister's house where Betty Parris and Abigail Williams lived; it was there that Griggs made his famous diagnosis.
The neighboring port, wealthier and more populous, where the court that tried the accused was held.
The Salem hill where nineteen people accused of witchcraft were hanged during the summer of 1692.
The Puritan territory of New England where Griggs lived and practiced medicine.
Typical Objects

A leather bag holding the practitioner's rudimentary instruments: lancets for bloodletting, cupping glasses and vials. Medicine relied chiefly on observation and the theory of the humors.

A small blade used to open a vein and perform bloodletting, the universal remedy of the day, believed to restore the balance of the body's humors.

At the heart of every Salem household, it served as the moral and spiritual touchstone. Within this framework of belief, the Devil and witchcraft were held to be tangible realities.

A cake made of rye and the urine of the afflicted girls, fed to a dog to “reveal” the witch. This old wives' remedy worsened the panic instead of calming it.

Printed books relied upon by the few physicians, blending astrology, herbal recipes and folk knowledge. The line between science and belief was blurred within them.

A symbol of the colonial justice that condemned the accused on the strength of “spectral evidence.” A physician's words could carry as much weight as a witness's testimony.

Daily Life
Morning
When he rose, Griggs often began the day with family prayer, like every Puritan household. Then he packed his bag to visit the sick scattered across the farms of Salem Village, sometimes several kilometers away on horseback.
Afternoon
The afternoon was spent at patients' bedsides: he observed symptoms, performed bloodletting, or prescribed herbal decoctions. With no laboratory or real scientific knowledge, diagnosis rested on experience and tradition.
Evening
In the evening, by candlelight, he consulted his few books of medicine and his almanac. Puritan evenings were sober, paced by Bible reading and rest, since entertainment was frowned upon.
Food
Colonial food was simple: corn porridge, rye bread, beans, salted pork, and vegetables from the garden. Fresh meat and sugar remained scarce; light beer and cider accompanied meals.
Clothing
Like well-off Puritans, he wore dark wool clothing, plain and buttoned high, with a wide-brimmed hat. The austerity of his dress reflected the religious values that forbade luxury and ostentation.
Housing
He lived in a timber house with a massive frame, heated by a large central chimney. The rooms were dark, the windows small, and the household included family and servants living under the same roof.
