Louis Schwartz, Waiter, Dies:
Sold $9-Million in War Bonds
"Send a Salami"
As "Louie the Waiter," working in the Sixth Avenue Delicatessen, between 55th and 56th Streets, Mr. Schwartz suited his tactics to his customers to persuade them to buy war bonds.
The bonds he sold paid for 66 P-47 Thunderbolt fighter planes and each bore the name "Louie the Waiter" and his sales record to that date.
Mr. Schwartz, a short, plump man with a bouncy walk and pink cheeks, was given to composing doggerel. His customers and his colleagues called him a poet, quoting one of his more famed creations, "Sent (sic) a Salami to Your Boy in the Army."

While classic Jewish delis are dwindling in number in New york, Katz's has kept going since 1888. By the time Katz's hung its famous World Was II sign, "Send a Salami to Your Boy in the Army," the place was already an institution.
My great grandparents also owned a Deli in NYC, not far from Katz’s. Family legend has it that Louis stole the slogan from my great grandparents, who first coined the term.
