When we think of JFK, we usually think of the motorcade in Dallas or the grainy footage of the moon landing speech. We see the tan, the white teeth, and that effortless "Camelot" vibe. But if you look at the John F. Kennedy date of birth, you find a story that isn't about power or polish. It’s about a skinny kid who almost didn't make it out of the nursery.
May 29, 1917.
That's the day. It was a Tuesday. Outside the windows of a modest gray house at 83 Beals Street in Brookline, Massachusetts, the world was in chaos. The United States had just entered World War I a few weeks earlier.
Inside? Rose Kennedy was giving birth to her second son.
The 3:00 PM Arrival
Jack, as he was called, arrived at exactly 3:00 PM. Honestly, if you visit that house today—it's a National Historic Site now—all the clocks are frozen at that exact moment. 3:00. It’s a bit eerie, but it’s how Rose wanted it when she restored the home in the late 60s.
He was born in the master bedroom. It wasn't a hospital birth because, back then, wealthy families like the Kennedys did things at home. Dr. Frederick Good delivered him.
But here is the thing: the "vibrant" JFK we remember was basically a myth in 1917.
He was a sick baby. Truly. Before he even turned three, he caught scarlet fever. It nearly killed him. In fact, throughout his life, he was given his last rites by a priest five different times. The first time was when he was a newborn.
Imagine that. The man who would eventually face down the Soviets during the Cuban Missile Crisis started his life being told he might not survive the week.
A Streetcar Suburb Childhood
Brookline wasn't the sprawling estate you’d expect. It was a "streetcar suburb." The house on Beals Street was comfortable but not huge.
You’ve probably heard the Kennedy family was "old money." That’s actually a common misconception. In 1917, Joe Kennedy Sr. was still clawing his way up. He was successful, sure, but he wasn't the titan of industry he'd become. They were Irish-Catholics in a Boston society that still looked down on them.
Jack shared a tiny bedroom with his older brother, Joe Jr. They had two twin beds and a small table for their meals.
It was a house of competition. Even as toddlers, the boys were pushed to win. Joe Sr. used to say, "We don't want any losers around here. In this family, we want winners."
Why May 29, 1917, Changed Everything
The John F. Kennedy date of birth matters because he was the first president born in the 20th century. That’s a massive distinction. Every president before him was born in the 1800s. They were Victorian-era men.
Kennedy was different. He was a child of the modern world.
He grew up with the radio. He grew up with movies. He was the first president who truly understood the power of an image. But that image of "health and vigor" was a carefully crafted mask.
His medical records, which weren't fully released until decades after his death, show a man who was almost constantly in pain. He had Addison’s disease. He had a "bad back" that required him to wear a heavy canvas brace. He even had one leg shorter than the other.
Sorta changes how you look at those photos of him sailing, right? He wasn't just enjoying the sun; he was often hiding a lot of physical agony.
The Mystery of the "Second Son"
If you were betting on a Kennedy to be president in 1917, you wouldn't have picked Jack.
Joe Jr. was the star. He was the athlete. He was the one the father groomed for the White House. Jack was the "bookish" one. Because he was so often stuck in bed with illnesses, he became a voracious reader. He loved stories of King Arthur and the Knights of the Round Table.
That’s where the "Camelot" idea eventually came from. It wasn't just a PR move; it was a reflection of the books he read as a sick kid in Brookline.
Practical Insights for History Buffs
If you’re researching JFK or planning a trip to see where it all started, here are a few things to keep in mind:
- Visit Brookline, not just Hyannis Port: Everyone goes to the Cape, but the Beals Street house is where the "real" Jack lived before the fame. It’s managed by the National Park Service.
- Check the Medical Context: To understand JFK, you have to understand 1910s medicine. The fact that he survived scarlet fever and multiple bouts of colitis as a child is actually a testament to the high-quality care his father’s money could buy.
- Look at the 1917 Draft: JFK was born the same year the U.S. started the draft for WWI. His father famously stayed out of the service, a point of contention that later fueled Jack’s own desire to prove himself in WWII on the PT-109.
If you want to truly understand the 35th president, stop looking at the end of his life for a second. Look at the beginning. Look at that Tuesday in May. It was a world of "No Irish Need Apply" signs and a sick kid who was never supposed to be the "standard bearer" for his family.

To dig deeper, you should look into the specific medical journals from the 1950s that first hinted at his Addison's disease. Comparing his public health image to his private reality offers a much more nuanced view of the man than any textbook will give you. You can also trace his early education at the Dexter School in Brookline to see how those early years shaped his legendary oratorical style.
