Solomon Joachim Chayim Halberstam (23 February 1832 – 24 March 1900) known from his acronym as ShaZHaH (שזחה), was an Austrian scholar and author.
His father, Isaac Halberstam, was a prominent merchant who devoted his leisure time to study, and left in manuscript a work which Solomon published in his honor under the title Siaḥ Yiẓḥaḳ, Lemberg, 1882.
This work contains also notices on the genealogy of Halberstam, who numbered eminent rabbis among his ancestors both on his father's and on his mother's side.
Halberstam was one of the directors and chief supporters of both the old and the new Meḳiẓe Nirdamim, the publications of which include contributions from him.
The greater part of them was acquired by Montefiore College, Ramsgate, England, while his large collection of printed books, and a considerable number also of manuscripts, was bought by Mayer Sulzberger and presented to the library of the Jewish Theological Seminary of America.
