BLT (BMT) Sandwich (bacon, lettuce and tomato)

The BMT sandwich (Bacon Mit Tomato) was named after the NYC subway line at least as early as 1936. Subway restaurants trademarked its "Italian B.M.T." sandwich (sliced Genoa salami, pepperoni, ham and vegetables) from 1967.

The BLT sandwich (bacon, lettuce, tomato) possibly comes from Chicago and was named after its famed Chicago Tribune columnist BLT, or Bert Leston Taylor (1866-1921). The "BLT" sandwich is first cited in print in 1941.

The initials "BLT" also stand for "Bites, Licks and Tastes." A BLT riddle was cited in print in 1994, with this version in 2001:

Q: How can you use a lighthouse, rose trellis, windstorm, dune, and Halloween costume to create something tasty?
A: Make a beacon, lattice, and tornado sand witch.


"BTL" was also used. "For the sake of brevity, 'B. T. L.' is still used for a bacon, tomato and lettuce sandwich" was printed in the Boston (MA) Daily Globe on September 3, 1951. "B. T. L. That's East Coastese for a bacon, tomato and lettuce sandwich" was printed in the Independent (Long Beach, CA) on May 28, 1964. "Btl" also stands for "bottle," so it's understandable how "BLT" became the popular combination of the letters.


Wikipedia: BLT sandwich
The BLT is a variety of sandwich containing Bacon, Lettuce, and Tomato. The sandwich traditionally has several strips of cooked bacon, leaves of lettuce (traditionally iceberg or romaine), and slices of tomato, all sandwiched between slices of bread, optionally toasted. Mayonnaise is the traditional condiment used.

The origins of the BLT are not fully known. The 1929 book Seven Hundred Sandwiches by Florence A. Cowles refers to a "bacon sandwich" though this recipe calls for green peppers and pickles but neither lettuce nor tomato. However, the book also mentions a "Bacon Salad Sandwich" which combines a creamed bacon salad (similar to chicken or tuna salad) with onion, lettuce and tomato.

Wikipedia: Brooklyn-Manhattan Transit Corporation
The Brooklyn-Manhattan Transit Corporation (BMT) was an urban transit holding company, based in Brooklyn, New York City, United States, and incorporated in 1923. It is now the BMT Division of the New York City Subway. Together with the IND, it is operationally described as B Division. The original BMT routes have the letters from J to R, as well as the Franklin Avenue Shuttle (S). The IND's B, D and F partly use BMT trackage, as does a short section of the A in Queens, while the W and Z supplement the N and J.

Italian B.M.T.® An old-world favorite. Sliced Genoa salami, pepperoni and ham and your choice of fresh vegetables and condiments served on freshly baked bread. Some say BMT stands for biggest, meatiest, tastiest. We wouldn’t disagree.

1 March 1936, New York (NY) Times, "Lexicon of the Soda Jerker" by Helen Dallis, pg. X10:
Some of the expressions are divided into idea families. When the bacon and tomato sandwich became "the BMT," the subway family started. It fell to the lot of the lettuce and tomato to be called "IRT," even though neither of the first two letters seem to stand for anything.
