DIMS'DAI.E, (Thomas, baron), celebrated for the 
practice of inoculation, was the fon of a furgeon and 
apothecary at Thoydon-Garnon in Elfex, where he was 
born in 1712. The family were of the religious fociety 
called quakers, and his grandfather had accompanied 
William Penn to America, but afterwards returned to 
England. Thomas was brought up under his father, 
and^ afterwards became a pupil at St. Thomas’s hofpital. 
He fettled at Hertford in 1734, and purfued the practice 
of the profeffion with increafing reputation. In the re¬ 
bellion of 1745, he was made alliftant to the medical de¬ 
partment in the army of the duke of Cumberland; and 
he continued with the army till after the furrender of 
Carlifle, when he refumed his fituation at Hertford, and 
took his degree as a phylician in 1761. As the inocula¬ 
tion for the fmall-pox had long formed a branch of his 
practice, his attention was peculiarly excited to the re¬ 
ports of the extraordinary fuccefs accompanying that 
operation, as improved by the MelTrs: Sultons and Smith, 
and then performed with Angular fuccefs, in the counties 
of Elfex, Suffolk, and Sulfex. The latter gentleman 
purlued the medical line at Horfham, and was the well- 
known author of the Antiquities of Stonehenge. He dif- 
covered the circumftances which he thought elfentially 
conducive to this fuccefs, and after full experience of 
their efficacy, he publiffied, in 1766, a treatife, intitled 
The prefent Method of inoculating for the Small-pox ; 
in which, with great clearnefs.and precifion, he laid be¬ 
fore the public the whole of his method, together with 
many judicious obfervations on points connected with 
the fubjedt. His work was received with uncommon in- 
tereft, and palfed through feveral editions. It was like- 
wife widely circulated upon the continent, and was tranf- 
lated into’all the principal languages of Europe. In 
1768, the emprefs of Riiffia, defirous of introducing the 
practice of inoculation into her dominions, refolved to fet 
the example to her fubjeCts, by fubmitting herfelf and 
her fon the grand duke to the hazards of the experiment. 
She naturally looked to England for a perfon worthy to 
be entrufted with this important bufinefs ; and her mi- 
miter in London was directed to Dr, Dimfdale, who im- 
a 
D I N 
dertook the office ; and, accompanied by one of his fons,- 
then a ftudent in phyfic, he arrived at P.eterfburgh in the 
month of July, 1768. The inoculation of the emprefs 
and the grand duke'took place in October and Novem¬ 
ber, with the moll defirable fuccefs. No phyfician in 
modern times, perhaps, has been fo munificently reward¬ 
ed. Befides an allowance of 2000I. for his journey, lie- 
received a gratuity of io,oool. and a penfion for life of 
500I. per annum, with the title of body-phyfician and 
aCtual counfelior of (late, and the rank of a baron of the 
Ruffian empire, perpetuated in his eldelt defcenda;»ts„ 
On his fon was conferred the fame rank, with a prefent 
from the grand duke of a gold fnuff-box fet with dia¬ 
monds. They had alfo permifiion to add to theirarmsa 
black wing of the Ruffian fpread-eagle on a gold fliield. 
After the recovery of his illufirious patients, a number 
of perfons of diltinCtion at Peterlburgh engaged him to 
inoculate their families; and at the requell of the e,m- 
prefs he undertook a journey to Mofcow for a fimilar 
purpofe. Upon his return home he was honourablv re¬ 
ceived by the king of Pruffia at Potfdam. This acceffion 
of fortune and dignity did not prevent him from refuming, 
practice at Hertford. In 1776 he publiffied, Thouglus 
on general and partial Inoculation ; and he purfued the 
fubjeCt in 1778, by Obfervations on the Introduction to 
the Plan of the Difpenfary for general Inoculation; and 
the different opinions on this topic produced a warm 
controverfy, which at length deviated into perfdnalities s 
and ceafed to be interefting. 
Baron Dimfdale, in 1780, entered into a new feene of 
public life, as reprefentative in parliament for the bo¬ 
rough of Hertford. On this occafion he refigned the 
practice of his profeffion, except in the way of gratuitous 
advice and affifiance. In ^Si’he publiffied Trails on 
Inoculation ; confiding of the particular narration of his 
journey to Ruffin, and the events attending the cafes of 
the emprefs and her fon; of the methods propofed by 
him for extending inoculation through the Ruffian em¬ 
pire ; and of additional obfervations to his former trea- 
tifes on inoculation. From thefe laft it appears, that the 
final practice of Dimfdale may be comprifed in the ufe 
of fluid matter for communicatingthe infection, little or 
no previous preparation, a moderately low diet from the 
time of inoculation, cool air and evacuants at the period 
of the eruptive fever, and moderate warmth at the time 
of maturation. This volume alfo contains valuable re- 
markson theepidemic fmall-pox, and other circumfiances 
belonging to the natural difeafe. Soon after its publi¬ 
cation he again vifited Ruffia, in compliance with a fum- 
mons from the emprefs to inoculate the two fons of the 
grand duke. In palling through BvulTels he was treated 
with great regard by the emperor jofeph, then in that 
city. He perfectly lucceeded in the object of his fecond 
journey, and was again munificently recompenfed. In 
1784 he was "again eleCted to reprefent the borough of 
Hertford in parliament. About this time he had the 
misfortune of lofingthe fight of both eyes from cataraCts. 
Fie fubmitted to the operation of extraction, performed 
by baron Wenzell, which proved completely fuccefsful. 
He retired from his parliamentary Italian in 1790, and 
thenceforth lived in tire bofom of his family and friends 
till December 30, 1800, when he died at the age of 
eighty-nine. Flis remains were depofited in the quakers’ 
burial-ground at Biffiop-Stortford. Fie was a member 
of the royal fociety, and vice-prelident of the Bath agri¬ 
cultural fociety.
