When Ted Kennedy collapsed from a seizure in May 2008, it wasn’t just a personal health crisis—it was a moment that focused the nation’s attention on a devastating disease. The diagnosis of glioblastoma, the same aggressive brain cancer that would later claim Senator John McCain, set off a 15‑month battle that ended with his death on August 25, 2009. But Kennedy’s story is far more than his final chapter: it’s a 47‑year Senate career, a family legacy that shaped American politics, and a resilience that earned him the title “The Lion of the Senate.”

What happened with Ted Kennedy?

Early life and political ascent

  • Born in 1932, the youngest of nine children of Joseph P. Kennedy Sr. and Rose Fitzgerald Kennedy (Biography.com).
  • Elected to the U.S. Senate in 1962 at age 30, filling the seat his brother John F. Kennedy vacated after winning the presidency (U.S. Senate biography).

Senate career overview

  • Served 47 years, becoming one of the longest-serving senators in American history (U.S. Senate biography).
  • Key legislation included COBRA, the Americans with Disabilities Act, and the No Child Left Behind Act (POLITICO obituary).
  • POLITICO described him as the “most accomplished legislator of his generation in the Senate.”

Chappaquiddick incident

  • On July 18, 1969, Kennedy drove off a bridge on Chappaquiddick Island, resulting in the death of his passenger, Mary Jo Kopechne. The incident became a major controversy and likely ended his presidential ambitions.

The implication: Kennedy’s early career was marked by both extraordinary achievement and a singular tragedy that shaped public perception for decades.

Bottom line: Kennedy’s legislative record and personal tragedy defined his public image, with his 47-year Senate career unmatched in modern American politics.

How did Ted Kennedy die?

Diagnosis of glioblastoma

  • On May 17, 2008, Kennedy suffered a seizure at his home in Cape Cod. Doctors at Massachusetts General Hospital discovered a malignant brain tumor (ABC News).
  • On May 20, 2008, his doctors announced the diagnosis as a malignant glioma (ABC News). The American Cancer Society later clarified that gliomas are a broad category of brain tumors (American Cancer Society statement).
  • A biopsy revealed the tumor was in the parietal lobe (MedicineNet).

Treatment and prognosis

  • Kennedy underwent surgery to remove the tumor, followed by radiation and chemotherapy.
  • He continued to work in the Senate during treatment, including delivering a speech at the 2008 Democratic National Convention.

Final months and death

  • He died at his home in Hyannis Port, Massachusetts, on August 25, 2009, at age 77 (MedicineNet).
  • The cause of death was glioblastoma (U.S. Senate biography).
Why this matters

Kennedy’s public battle with glioblastoma made the rare cancer a household name and spurred conversations about research funding. The same disease would later claim Senator John McCain exactly nine years later, on the same calendar date (TIME report).

The pattern: Kennedy’s 15‑month survival matched the typical prognosis for glioblastoma, but his determination to remain active in the Senate until the end became part of his legacy.

Bottom line: Kennedy’s glioblastoma diagnosis and death highlighted both the disease’s grim prognosis and his resilience in continuing Senate work during treatment.

How long did Ted Kennedy live after being diagnosed with glioblastoma?

Survival timeline

  • Kennedy lived 15 months after his diagnosis in May 2008, passing away on August 25, 2009.
  • His glioblastoma was classified as a malignant glioma, a category with a median survival of 12–15 months (TIME report).

Comparison to typical glioblastoma survival

  • Kennedy’s survival time fell within the typical range; he received aggressive treatment at a top-tier facility.
  • His case, like John McCain’s later, highlighted the grim reality of glioblastoma: even with the best care, the disease is nearly always fatal within a few years.
The catch

Despite the similar survival time, Kennedy’s age (77) and the tumor’s location meant he was never a candidate for some experimental therapies that younger patients might try. The medical community used his case to emphasize the need for more research into glioblastoma treatments (CancerNetwork report).

The trade-off: Kennedy’s public profile gave researchers a platform to educate the public, but the disease itself remained as deadly as ever.

Bottom line: Kennedy’s 15-month survival fell within typical glioblastoma parameters, and his case underscored the need for continued research into treatment options.

Did Joan Kennedy go to Ted Kennedy’s funeral?

Joan Kennedy’s attendance at funeral

  • Joan Kennedy, Ted’s first wife, did attend the funeral on August 29, 2009, at the Basilica of Our Lady of Perpetual Help in Boston. Reports indicate she was present and sat with the family.
  • The couple had divorced in 1982 after 24 years of marriage, but remained on cordial terms.

Relationship after divorce

  • After their divorce, Joan Kennedy struggled with alcoholism but later sought treatment and maintained a low profile.
  • She was at his bedside during his final days, according to family statements.

The pattern: The Kennedy family’s ability to unite during crises, even after personal fractures, remained a defining trait.

Bottom line: Joan Kennedy’s presence at the funeral and at his bedside showed the family’s capacity to set aside past differences during times of loss.

What happened to Ted Kennedy’s daughter Kara?

Kara Kennedy’s life

  • Kara Anne Kennedy was the eldest of Ted Kennedy’s three children. She worked as a television producer and was active in charity work.
  • In 2002, she was diagnosed with lung cancer and underwent surgery and chemotherapy.

Death in 2011

  • Kara Kennedy died of a heart attack on September 16, 2011, while exercising at a health club in Washington, D.C. She was 51 years old.
  • Her death came just two years after her father’s, adding another layer of tragedy to the family’s history.
What to watch

Kara’s lung cancer earlier in life and her father’s brain cancer raised questions about genetic predispositions in the Kennedy family, though no direct hereditary link for glioblastoma has been established.

The catch: Kara’s death, while not caused by cancer, highlighted the cumulative health battles the family endured.

Bottom line: Kara Kennedy’s death from a heart attack in 2011 added another chapter to the Kennedy family’s history of health struggles and personal tragedy.

Quotes on Ted Kennedy’s legacy

“The work goes on, the cause endures, the hope still lives, and the dream shall never die.”
