GENEALOGICAL NOTES ON CHARLES FREDERICK
WIESENTHAL
The Society for the History of the
Germans in Maryland recently re-
ceived new material on Charles Fred-
erick Wiesenthal (1726-1789), the
most prominent Baltimore German in
the eighteenth century.* Up to the
present the only facts concerning his
early life were place and year of birth:
Prussia, 1726. Eugene F. Cordell, an
authority on medical history in Mary-
land, said "we possess no further de-
tails of his life in his native land."
Now we can say a little more about
the first twenty-five years of his life,
i. e. before he emigrated to America.
The father, Johann Mattheus Wie-
senthal, was a barber in the city of
Pasewalk in Pomerania, a Prussian
province. Through a new Medical
Regulation, issued in 1729, he was
confirmed as a surgeon. Barber-sur-
geon was not an unusual professional
combination in the eighteenth cen-
tury. In this dual capacity, J. M.
Wiesenthal was associated for several
years with the Prussian regiment of
the Ansbach-Bayreuth lancers. Due
to this connection he was privileged
to send his two sons Johann Christoph
and Karl Friedrich (Charles Fred-
erick) to the "regimental school"
which was on a considerably higher
level than the ordinary schools.
Johann Mattheus Wiesenthal proba-
bly took part in the first and second
Silesian campaigns of Frederick the

Great (1740/45). He met his death
some time before 1747. His widow
died in Pasewalk, in October 1767.
Johann Mattheus Wiesenthal had
four children: Johann Christoph
(born 1724);; Karl Friedrich (bap-
tized August 12, 1726); Samuel Gott-
lieb (baptized September 11, 1729);
Euphemia (baptized November 12,
1732). [See genealogy below.]
No material is available on Karl
Friedrich Wiesenthal's schooling and
medical training. Neither he nor his
brother are mentioned in the roster
of the Prussian Collegium Medico-
Chirurgicum of Berlin, founded by
Frederick the Great for the training
of military surgeons. Thus it is not
impossible that Wiesenthal never
completed the official medical curricu-
lum, in which case he would deserve
all the more credit for his subsequent
medical accomplishments in Balti-
more. On July 4, 1747, he married
Christina Regina Talcho, the daughter
of a Berlin brewer. (Excerpt of the
marriage register of the Protestant
Jerusalem Church of Berlin, Procl.
and Copul. 1747, Dom. 3, 4 and 5 p.
Trin.). After the wedding the couple
went briefly to Pasewalk where the
wedding was recorded in the register
of the Lutheran Church (July 27,
1747).
Some time before 1747, Wiesenthal
must have moved to Strasburg in the
Uckermark. Here he practiced sur-
gery for a number of years, probably
up to the time of his emigration. The
scroll of citizens of Strasburg (Ucker-
mark) records that on October 2,
1747 the surgeon Carl Friedrich Wie-
senthal, after having paid one Taler
and six Groschen, became a citizen of
Strasburg. Seven months after the
wedding, with inappropriate haste,
the first child arrived: Carolina Fried-
erica, born August 27, 1747 and bap-
tized four days later in the Evangeli-
cal Church of St. Mary's at Strasburg.
(Register of baptisms 1747, no. 49).
A second daughter followed Novem-
ber 26, 1748: Florentine Amalie
Louise. (Reg. of bapt. 1748, no. 70).
However, the little girl died from
small pox a few months later, as re-
corded in the death register of St.
Mary's Church (1749, July 22, no.
33). The first son was born in 1750:
Johann Matthias Wiesenthal, whose
baptism was recorded in the register
of the Lutheran Church of Pasewalk.
A second son followed two years
later: Christian Friedrich Carl, born
March 12, 1752 and baptized in Stras-
burg, March 16, 1752. The register of
baptisms (1752, no. 12) added the
revealing note that the boy was bap-
tized in the absence of his father. It
is possible that at that time the
father had already left for the Ameri-
can colonies, however, there is no in-
dication as to whether, when and why
the father departed and why he may
have left the family behind. Among
the godparents of all the Wiesenthal
children we find the names of people
of considerable social standing:
mayors, high officials, physicians and
members of the aristocracy, which
may justify some conclusions as to
the social prestige of the Wiesenthals.
All this material has been collected
by one of the descendents of Charles
Frederick Wiesenthal's older brother,
Mr. Karl Wiesenthal of Stuttgart-
Vaihingen, Germany, who kindly put
it at the disposal of our Society. The
material was gathered long before the
war and the present division of Ger-
many and came from church and
state archives which now are either
destroyed or inaccessible to genealo-
gists and researchers, such as the
Prussian State Archives, the City Ar-
chives of Strasburg, Church archives
of Pasewalk (Pomerania), Strasburg
(Uckermark) and Berlin. All the
more we appreciate Mr. Karl Wiesen-
thal's help. The copies of the various
documents which were received from
him in 1950/51 were deposited in the
archives of Zion Church in Baltimore,
since this is the congregation in whose
early history Charles Frederick Wie-
senthal played such a distinguished
role.
Unfortunately, we cannot with cer-
tainty put down the Wiesenthal fam-
ily history after the doctor's arrival

WIESENTHAL GENEALOGY
(This chart was  compiled by  Mr.  Karl Wiesenthal of  Stuttgart-Vaihingen)
in Baltimore. Zion Church, the Ger-
man Lutheran congregation with
which he associated himself, kept no
records before 1786; its records after
that date are extremely brief and un-
informative. Charles Frederick Wie-
senthal's death is recorded on June 1,
1789, the death of a "Frau Wiesen-
thal" (without first name) on July 3,
1805.
We never hear of the Wiesenthal
children born in Germany between
1747 and 1752. There is a great deal
of information about a son, Dr. An-
drew Wiesenthal, evidently born in
Baltimore in 1762. He studied medi-
cine in Philadelphia and London
(1786-1789). After his return to
Baltimore he regularly delivered lec-
tures on anatomy, pathology and
surgery. His return from England,
says Cordell, "infused new life into
the profession of Baltimore." (Cor-
dell, Medical Annals, 17, 18, 171, 173,
664, 665, 668, 669; Maryland Gazette,
March 16, 19, 30, 1790). When in
November 1789 the Medical Society
was reorganized Andrew Wiesenthal
became secretary-treasurer and libra-
rian. In the same year he was ap-
pointed attending physician at the
almhouse, in 1796 he became Judge of
the Orphans' Court. He also figured
prominently in the history of the Ma-
sonic lodge. A British periodical re-
ported his discovery of the parasite of
trachero-bronchitis in fowls. (London
Medical and Physical Journal, Octo-
ber 1799).
Andrew Wiesenthal's family his-
tory is very scanty. Cordell says that
after his return from Europe he mar-
ried (1789) Sarah Van Dyke of the
Eastern Shore. Their offspring appar-
ently was Thomas Van Dyke Wiesen-
thal, who was born in Chestertown,
Maryland in 1790, became a surgeon
in the United States Navy and died
in Portsmouth, Virginia, March 21,
1833. (Cordell, Annals, 621.)
The records of Zion Church report
that two sons were born to Andrew
Wiesenthal: Carl Frederic on January
3, 1797 and Andrew Haworth on
January 25, 1798. Since a Mr. An-
drew Haworth appears occasionally
on the pages of the Zion records it is
not impossible that Andrew Wiesen-
thal married a second time, this time
the daughter of Andrew Haworth.
The two children did not live long:
"Dr. Wiesenthal's Kind" (no name)
died June 20, 1797; little Andreas
(Andrew) Wiesenthal, 15 months old,
passed away on April 27, 1799. A few
months before that date, December
2, 1798, Zion Church recorded the
death of their father, Dr. Andrew
Wiesenthal. The church record gives
his age as 27 years instead of 36, ob-
viously an error since this is incom-
patible with Cordell's remark about
his return from England and its effect
on the medical profession in Balti-
more. The fact that during the con-
cluding years of the century yellow
fever raged in Baltimore may account
for the fact that within three years
there were three crosses in the family
history.
The Wiesenthal family history is
one of the stories which becomes more
contradictory and confused the more
material we get. Cordell mentions (p.
171) a young medical student Fred-
erick Dalcho, born in London 1770,
according to Cordell the son of Eliza-
beth Wiesenthal, a sister of Charles
Frederick Wiesenthal. The Wiesen-
thal genealogy shows no sister Eliza-
beth. However, C. F. Wiesenthal's
wife (first wife?) was Christina Regina
Talcho, a name which also appears as
Dalcho and Telchow. Frederick Dal-
cho came to Baltimore in 1789 at the
invitation of his uncle, yet it may be
that the family relationship was not
as simple as Cordell thought. He may
have been a nephew of Charles Fred-
erick Wiesenthal, not a son of Wie-
senthal's sister, but probably a son of
a brother-in-law through his marriage
to Christina Regina Dalcho (Talcho).
Whether there are still descendants
with the name of Wiesenthal we do
not know. Eugene Cordell, almost
fifty years ago, mentioned a "late
Miss Wiesenthal of Boston." (Johns
Hopkins Hospital Bulletin, 1905, XVI,
no. 177). If our readers know of Wie-
senthal descendants, we would appre-
ciate information.
