Friedman, Aaron Zebi. Tub Taam or a Vindication of the Jewish Mode of Slaughtering Animals for Food Called Shechitah. Translated from the Hebrew by Laemlein Buttenwieser.

Aaron Tzvi Friedman (1822-76), a shochet, or ritual slaughter in New York City, responds to the charge by Henry Bergh, President of the Society for the Prevention of Cruelty to Animals, that shechitah is inhumane.“According to a family legend, the English translation of this work convinced President Ulysses S. Grant to eat only kosher meat.” See Y. Goldman, Hebrew Printing in America, number 1092.
