Ladyzhenskaya (née Weinstein) Dvoira Leybovna (10 May 1909, Bratslav, Vinnytsia Region, Ukraine) — homemaker.

Dvoira Ladyzhenskaya was born into the family of a footwear supplier, Leyb Gershkovich Vaynerman (1863–1935, Bratslav), and Khana Moshkovna Vaynerman (1868–1930, Bratslav). She completed two grades of the local school (1921) and was engaged in household work.

In her marriage to Getsei Pinkovich Ladyzhensky (b. 1904, Tulchyn, Vinnytsia Region, Ukraine), she had two children — Liza Getselevna Weisberg (née Ladyzhenskaya) (b. 1928, Tulchyn) and Lev Getselevich Ladyzhensky (b. 1936, Tulchyn).

In 1941, the family failed to evacuate; together with her husband and two children, she was imprisoned by the Nazis in the Pechora concentration camp for Jews, where her husband was executed that same year in Tulchyn.

In her second marriage to Wolf Srulevich Blech (b. 1900, Riga), two daughters were born: Anna Wolfovna Milman (née Blech) (b. 1946, Tulchyn) and Polina Wolfovna Moldavskaya (Blech) (b. 1950, Tulchyn).

In 1979, Dvoira Ladyzhenskaya received permission to emigrate to Israel, where since the 1920s her cousin Ester Ron (b. 1908, Bratslav) had been living.
