If you walk into a bar today and see a black-and-white photo of five guys in sharp tuxedos laughing over martinis, you already know them. You might not know their birthdays or their middle names, but you know the vibe. They owned Las Vegas. They owned the radio. Honestly, they kinda owned the 1960s. But when people ask who is in the Rat Pack, the answer usually depends on whether you’re talking about the famous "Summit" crew or the original group of Hollywood rebels that started way before the neon lights of the Sands Hotel ever flickered to life.
Coolness personified.
Most people think of Frank Sinatra and his buddies. That’s the "Summit" version, the one that defined the JFK era. But history is a bit messier than a highlight reel. Before Frank was the "Chairman of the Board," the Rat Pack was actually centered around Humphrey Bogart. Yeah, Casablanca Bogie. It was a literal club in Holmby Hills where Lauren Bacall was the "Den Mother" and Sinatra was just a member, not the leader.
But let's be real. When you search for this, you're looking for the five icons who made "The Sands" the center of the universe.
The Core Five: Defining the Summit Era
To understand who is in the Rat Pack, you have to look at the 1960 line-up. This wasn't just a group of friends; it was a traveling circus of talent, booze, and surprisingly sharp business instincts.
Frank Sinatra
He was the engine. Without Frank, there is no Rat Pack. By the mid-50s, Sinatra had clawed his way back from a career slump and was basically the most powerful man in entertainment. He didn't like the name "Rat Pack," actually. He preferred "The Summit" or "The Clan," though the latter was dropped for obvious, uncomfortable reasons. Sinatra brought the discipline. Despite the onstage drinking (which was often just iced tea, despite the legend), Frank was a perfectionist. If you were in his circle, you showed up on time and you sang your heart out.
Dean Martin
The "King of Cool." If Frank was the boss, Dean was the guy who didn't care who the boss was. That was his whole charm. Dean Martin’s persona was the lovable drunk, but in reality, he was a family man who’d rather be playing golf than partying until 4:00 AM. On stage, he was the perfect foil to Sinatra’s intensity. He’d stumble in, crack a joke about Frank’s ego, and then deliver a vocal performance that made everyone else look like they were trying too hard. He was the secret sauce.

Sammy Davis Jr.
The most talented man in the room. Period. Sammy could dance better than anyone, play multiple instruments, mimic any voice, and out-sing most of the charts. He also had the hardest road. Dealing with the rampant racism of the era—often while his "friends" made jokes about it on stage that haven't aged well—Sammy was the one who broke the color barrier in Vegas lounges. Frank famously refused to play hotels that wouldn't let Sammy stay in a room there.
Peter Lawford
The "British Connection." Lawford was an actor, but his real value to the group was his brother-in-law: John F. Kennedy. Lawford was the bridge between Hollywood royalty and the actual White House. He was the "Newford" of the group, often the butt of the jokes, and eventually, the one Frank kicked out of the circle when the Kennedy family distanced themselves from Sinatra’s alleged mob ties.
Joey Bishop
The "Hub of the Big Wheel." Joey was a comedian who kept the show moving. While the others were ad-libbing and getting wild, Joey was the one making sure the timing worked. He wrote a lot of the "impromptu" material. He was the straight man. Without Joey, the shows would have just been five hours of drunk guys yelling; he gave it a structure that worked for a paying audience.
The "Mascots" and the Holmby Hills Roots
It’s a mistake to think it was only those five. If we're being historically accurate about who is in the Rat Pack, we have to mention the women and the early adopters. Shirley MacLaine was basically an honorary member—she appeared in Ocean’s 11 and was one of the few people who could keep up with their banter without being intimidated.
Then there’s the Bogart era.
In the mid-1950s, the original group included:
✨ Don't miss: Shamea Morton and the Real Housewives of Atlanta: What Really Happened to Her Peach
- Humphrey Bogart (The Rat in Charge)
- Lauren Bacall (Den Mother)
- Sid Luft and Judy Garland
- David Niven
- Swifty Lazar (the legendary agent)
Legend has it that Lauren Bacall looked at the group after a long night in Vegas and said, "You look like a goddamn rat pack." The name stuck. When Bogie died in 1957, Frank took the reins, moved the headquarters from a private home to the stage of the Sands Hotel, and narrowed the roster down to the performers we recognize today.
Why the Lineup Still Matters
This wasn't just a boy's club. It was a shift in American culture. Before the Rat Pack, performers were expected to be formal. You came out, you sang, you bowed, you left.
The Rat Pack changed that. They brought the "after-party" onto the stage. They made the audience feel like they were sitting in on a private joke. It was meta before meta was a thing. If Dean Martin forgot a lyric, he didn't apologize; he made fun of the song. If Sammy started a dance routine, Frank might sit on a stool and read a newspaper. This "controlled chaos" is why they stayed relevant.
They also had a massive impact on the civil rights movement, though it’s nuanced. Sinatra used his muscle to desegregate the Las Vegas Strip. He made it clear: if Sammy can’t walk through the front door, the whole group walks out. That’s real power used for something better than just selling records.
The Fallout: How the Pack Dissolved
The end wasn't a clean break. It was a slow fade.
The first crack was Peter Lawford. In 1962, Bobby Kennedy told JFK to stop staying at Sinatra’s house because of Frank's associations with Sam Giancana. JFK stayed at Bing Crosby’s place instead. Sinatra was furious. He blamed Lawford, the "link," and never spoke to him again. Lawford was out.

Then the music changed. The Beatles landed in 1964. Suddenly, the tuxedos and the swing music felt like "your dad’s music." The Rat Pack tried to keep up—Dean Martin actually knocked the Beatles off the top of the charts with "Everybody Loves Somebody"—but the cultural tide was turning toward rock and roll and the counterculture.
By the time they tried a reunion tour in the late 1980s (The "Together Again" tour), the magic was different. Dean Martin left the tour after just a few shows—he was grieving the death of his son and honestly, he just didn't want to be there. Liza Minnelli stepped in to fill the gap, but it wasn't the same.
Actionable Insights for Fans and Historians
If you’re looking to dive deeper into the legacy of the Rat Pack, don’t just watch the movies. Ocean’s 11 (the 1960 original) is a fun time capsule, but it’s actually a pretty slow movie by modern standards. Sergeants 3 and Robin and the 7 Hoods are the other "Pack" films, but they're mostly just excuses for them to hang out on camera.
What you should actually do:
- Listen to "Live at the Sands" (1966): This Sinatra album features the Count Basie Orchestra and captures the exact energy of the era. The banter between songs gives you a better sense of their chemistry than any movie script ever could.
- Watch the "The Rat Pack" (1998 HBO Movie): While it's a dramatization, Ray Liotta (as Frank) and Don Cheadle (as Sammy) do an incredible job of showing the dark side of the fame and the political pressure they were under.
- Study the business of Vegas: Understand that the Rat Pack didn't just play Vegas; they built it. They took points on the casinos. They were some of the first entertainers to understand the value of "residency" and ownership over a simple paycheck.
The Rat Pack was a moment in time that can't be recreated. You can put five guys in suits today, but without the specific post-war optimism and the raw talent of people like Sammy and Dean, it’s just a costume. They were the last of the true "Vegas Vultures," and their influence still echoes in every residency from Adele to Bruno Mars.
To truly understand the history of American entertainment, you have to know their names. Sinatra, Martin, Davis Jr., Lawford, and Bishop. They were the ones who turned a desert oasis into the entertainment capital of the world. Even if the tuxedos are gone, the "cool" they invented isn't going anywhere. For anyone digging into the archives, start with the music; the rest is just noise.
