Daniel Sennert

 (25 Nov.1572- 21 July 1637)


Occupation: Artisan

His father, Nicolaus Sennert, was a shoemaker fromLaehn, Silesia. He was sixty-seven when Daniel Sennert was born.

No firm information on financial status.






Schooling:Wittenberg, M.A., M.D.; Leipzig, Jena, Franfurtan Order, Basel

Attended schools inBreslau.

1593, enrolled at theUniversity of Wittenberg. Received his M.A. in 1598. I assume a B.A.

Studied medicine for three years atLeipzig, Jena, and Frankfurt a. d. Oder.

1601, he entered medical practice under the supervision of Johann Georg Magnus.

Made a short stay at theUniversity of Basel.

1601, he received his M.D. from theUniversity of Wittenberg.


Affiliation: Lutheran (assumed)

Claude Bonnet, a professor atAvignon, produced an expurgated edition of his works suitable for use by Roman Catholics in 1655.

Sennert was acquitted from the charge of heresy levelled by Johannes Freiburg, professor of medicine at Helmstaedt. The charge was made because Sennert held that the souls of animals as well as men were created by God out of nothing.

Scientific Disciplines

Primary: Medicine, Chemistry, Natural Philosophy

Sennert's first book was Institutiones medicinae, 1611, and later there were other medical works.

Epitome scientiae naturalis, 1618, and Hypomnemata physicae, 1636, both dealt with general issues in natural philosophy. He contributed to the revival of atomism.

Sennert was influenced by Paracelsus without being truly a Paracelsan; he wrote influentially on chemistry.

Sennert's collected works alone went through nine editions within the space of forty years, and individual works were also republished.

Means of Support

Primary: Medicine, Academia

He practiced medicine while still a student (see above).

1602-47, professor of medicine,University of Wittenberg. He was Dean of the medical faculty six times during that period.

I assume he also practiced medicine because he is referred to as having served as a physician inWittenberg and having been as well-known as a physician as a teacher. It is recorded that Sennert remained at his post in Wittenberg through seven plagues and died in the eighth.


Types: Eccesiastic Official, Academic, Court Official, Aristrocrat

Perhaps Johann Georg Magnus served as a patron of sorts, though I have no evidence of their relationship other than the fact that Sennert practiced under him.

The 1619 edition of De Chymicorum cum Aristotelis et Galenicis consensu ac dissensu is dedicated to the Archbishop of Magdeburg.

He could have received the chair atWittenberg only from the court. However, the sources attribute the appointment to Johann Jessen, a professor in Wittenberg. Sennert did become the personal physician to the Elector of Saxony, Johann Georg, after treating him successfully.

Ramsauer mentions Sennert's medical service to a wide range of aristocrats and rulers.
