NOTE:
As I understand it, Florence Nathan was the assistant to, and eventually
married, the owner of the company that manufactured Eisenberg jewelry. Her
name is on the patents, but she did not actually do the design work.

PURPLE and clear
rhinestones unsigned brooch. This is NOT an Eisenberg, but is so very
similar. It is a good example of why we must be very careful in identifying
unsigned pieces by patents drawings.

Regarding the attribution of the Florence Nathan patents to Eisenberg
Jewelry, Jim Katz says, "On page 179 of Brunialti’s book, A
Tribute to America, there is a February 1942 Vogue advertisement. Under
the ad the Brunailti’s state, "Eisenberg jewelry designed by Florence
Nathan." Two of the patents are identical with two of the pieces in the
ad, items "H" (bow pin) and "D" (bracelet). Even though the ad states
"Eisenberg Ice" in its title, inside it says, "Each Piece Hallmarked
Eisenberg Original". Also the patents were all filed together and granted
in May of 1942.

Bobye Syverson says that Florence Nathan was not actually a designer,
but was the wife of the owner of Manhattan company Fallon and Kappel who
manufactured Eisenberg jewelry at the time. Florence was the assistant
to Mr. Kappel. In 1943, Florence married Murray Silverman, who joined F&K
shortly after World War II and was in charge of production. When Mr. Kappel
became sick in the late 40s, the Silverman’s bought the business from him.

the Eisenberg designer.)
