Věra Kohnová (26 June 1929 – 1942) was a Jewish girl who was deported with her family first in January 1942 from Plzeň to a concentration camp in Theresienstadt and in March 1942 to the Izbica Ghetto in Poland.

The diary, in which she watched the last months of life of the Jewish inhabitants of Plzen as a child, she stopped writing a few days before her deportation to Theresienstadt.

Melanie Langerová was born in Dobřív near Rokycany, where her father David Langer, originally a teacher from Dolní Cetno near Mladá Boleslav, was a shopkeeper, tobacconist, and a pubkeeper.

In addition to Rudolf Kohn, their paternal uncle, Hanka and Věra also had a maternal grandmother named Otýlie Langerová.
