Zvi Hirsch Chajes (Hebrew: צבי הירש חיות - November 20, 1805 - October 12, 1855; also Chayes or Hayot or Chiyos) was a Galician talmudic scholar.

[2] In this position, he fought against innovations introduced into Judaism at that time, and opposed the increasing conservatism among his Orthodox colleagues.

Chajes died prematurely in 1855 at age 50, three years after he was appointed to the post of rabbi of Kalisz (Kalish), Poland.

"There are few modern works dealing in detail with the Halakha or the Aggadah which have not profited by the labors of Chajes, although his name is often passed over in silence.

His Introduction to the Talmud is especially noteworthy..."[1] Dr. Bruria Hutner David described Chajes as "Traditionalist and Maskil" - as the subject of her PhD thesis.
