Izzy Einstein and Moe Smith

Isidor "Izzy" Einstein (1880–1938) and Moe W. Smith (1887–1960) were United States federal police officers, agents of the U.S.

[2] He grew up speaking Yiddish and likely was educated in a yeshiva; he also learned Hungarian, Polish and German, together with a smattering of other European languages.

[5] The ratification in 1919 of the amendment to establish Prohibition in the United States required federal and local police forces to recruit new members rapidly in order to enforce the law.

With no background in law enforcement, but speaking several languages (Yiddish, Hungarian, German, Polish, with a little Russian, French, Spanish and Italian) in addition to English, Einstein signed up as Prohibition Agent No.

Their disguises included appearing as "streetcar conductor, gravedigger, fisherman, iceman, opera singer" and as the state of Kentucky delegates to the Democratic National Convention of 1924 held in New York, where they found only soda being served.

[5] As Prohibition Bureau agents, they were the most famous and successful, known nationally for making thousands of arrests and gaining a high rate of convictions.

[8] Einstein and Smith used the press to build support: They frequently scheduled their raids to suit the convenience of the reporters and the newspaper photographers, and soon learned that there was more room in the papers on Monday mornings than on any other day of the week.

One Sunday, accompanied by a swarm of eager reporters, they established a record by making seventy-one raids in a little more than twelve hours.

[5]In November 1925, the partners were among 38 men laid off from the New York office after a reorganization plan announced by General Lincoln C. Andrews of the national bureau.

[5][9] Andrews was reported as disapproving of Prohibition agents who gained publicity, and Einstein and Smith's exploits had been well covered by the press, both tabloids and major papers such as The New York Times; their successes were sensational.

As Time magazine wrote at the time, The public which looked upon them with as much delight as ever it looked on Robin Hood was denied their adventures — adventures as thrilling as those of Sir Launcelot, as those of Richard Cœur de Lion, as those of Don Quixote de la Mancha.
