Today marks 110 years since Jewish businessman Leo Frank z”l was lynched by a hate-filled mob in Georgia two years after being falsely accused and unjustly convicted of murder in a trial marred by antisemitism.

ADL was founded the same year that Leo Frank was arrested, and the trial only confirmed what the organization’s founders already knew – American Jews needed an institution that would combat antisemitism and all forms of hate.

Over the years, ADL fought to clear Frank’s name, and he was finally pardoned posthumously in 1986
