There may be a better word to describe what I’m shooting for but a few examples ought to make it clearer. Not just Cafe Society folks, either. That’s why here.
Billy Bob Thornton
Joe Don Baker
Helena Bonham Carter
Mary-Louise Parker
Billie Sol Estes
David Allan Coe
Who all can you add to the list?
John Wilkes Booth
Catherine Zeta-Jones
Alexander Graham Bell
Kristin Scott Thomas
Jennifer Jason Leigh
Evan Rachel Wood
Sarah Jessica Parker
Neil deGrasse Tyson
David Hyde Pierce
Ralph Waldo Emerson
Charles Foster Kane ( 
)
John Foster Dulles
Somebody want to start a new thread on folks known best as initials?
Like JFK
LBJ
GWB
And another one for people with the middle name The! 
Does Charles Emerson Winchester count?
Krusty The Clown
John Quincy Adams
John Logie Baird
Arthur Leigh Allen
Vicki Butler Henderson
Tara Palmer Tompkinson
Edgar Allan Poe.
Rob Roy McGregor
Robert Louis Stevenson.
George Dubya Bush
Barack Hussein Obama
Does Michael J. Fox count? How about Robert Griffin The Third?
Neil Patrick Harris
I could go either way, so it’s up to the individual what to include as part of the ever-so-vague theme!
Lee Harvey Oswald
Robert Louis Stevenson
Frank Lloyd Wright
Julia Louis-Dreyfus
There’s the theory that assassins and mass murderers often come to be known by their full names (e.g. John Wayne Gacy, a bunch of others I can’t think of now). I once read an explanation for this theory, but that too is escaping me at the moment.
Helen Mirren’s Tits?
As a young man it was always a badge of quality for a movie.
“Have you seen The Long Good Friday?”
“Oh, yeah”
“Any good?”
“Of course, it’s got Helen Mirren’s tits in it”
Martin Luther King
Who, interestingly, was just David Pierce until the *Frasier *showrunners wanted to dress him up a little.
Just to concur on another comment above, famous murderers often end up being known by all three names when they may have never been called that way in their lives. LHO was just Lee Oswald until November 22nd, 1963.
Florence Foster Jenkins.
Sarah Michelle Gellar
Something I’ve noticed from Civil War books, they nearly always show the middle initial or middle name:
Ulysses S Grant
Joseph E Johnston
George B McClellan
William Tecumseh Sherman
Nathan Bedford Forrest
George Armstrong Custer
J.E.B. Stuart
A.P. Hill
There are some exceptions, but I don’t think I’ve EVER seen or read “General Robert Lee”
Was there an 1860s reason middle initials were common? I notice most are generals, was there an upper-class reason for a prominent middle initial/name? Abraham Lincoln, with humble upbrinings, didn’t have one.
