[Louis Brandeis] at the age of 57 decided to become the head of the American Zionist movement was more influential than anyone else in the 20th century in persuading Woodrow Wilson to recognize a Jewish homeland in Palestine.

Do you think Bernie Sanders, for example, is citing Theodore Roosevelt as the progenitor of his critique of the banks when actually Roosevelt wanted to keep the banks together and regulate them.

I was very much influenced by a great book by the scholar Neil Richards called Intellectual Privacy, that [Louis] Brandeis changed his mind on the proper balance between dignity and free speech.

I'd say that [Louis] Brandeis practiced a kind of a "living originalism," to use the title of Jack Balkin's great book. He said you start with the paradigm case, which in the case of the Fourth Amendment was these general warrants or writs of assistance, but you define it at a level of abstraction that you can take it into our age and make it our own.

He's [Louis Brandais] so suspicious of bigness in government as well as business that he mistrusts even really top-down reforms at the state level. The most inspiring part of his legacy to me is his belief in the imperative and duty of self-education on behalf of citizens.

Louis Brandeis really inspired me to write this book [Louis D. Brandeis: American Prophet]. It was a crazy deadline. The editor said I'd miss the hundredth anniversary unless I pumped the thing out in six months, because I'd been delaying and dilly dallying for so long. So he both inspired me to get up early and write.

The historical resonances are sharp. [Louis] Brandeis is nominated on Jan. 28, 1916. Confirmed on June 1. Waits 125 days between nomination and confirmation, which remains an unbroken record, although Merrick Garland will surpass it in July, if my math is right. Anti-Semitism was definitely not the central reason for the opposition, which tended to focus more on his anti-corporate radicalism, but it was a theme.
