John-Caleb Bradberton

John-Caleb Bradberton was a chemist and business magnate before the Great War, best known as the inventor of the Nuka-Cola soft drink and CEO of the Nuka-Cola Corporation.


Inventing Nuka-Cola

Main article: Nuka-Cola

Bradberton was only an amateur chemist when he began developing what would become the nation's most popular soft drink in 2042.[1] It took him nearly two years, and the help of multiple other organic chemists he would later call his "Beverageers," but in late 2042, Nuka-Cola became a reality. Within merely a year, Nuka-Cola was the top-selling soft drink in the United States.[1][2][3]

On Memorial Day weekend of 2049, Bradberton watched on as hundreds of people enjoyed his soft drink at a fairgrounds; he remarked that "A day like this should be every day!", inspiring the idea of his theme park, Nuka-World. The success of Nuka-Cola was so immense that Bradberton was able to fund and build the entire theme park in less than a year, with doors opening to Nuka-Town USA and Kiddie Kingdom on May 1, 2050.[4]

With over 40,000 visitors admitted into the park at its grand opening, the park was an instant success and more attractions were planned to be added to Bradberton's park in the coming years. This included Dry Rock Gulch in 2058 and Safari Adventure in 2067, both of which essentially doubled the number of visitors to the park immediately. The Galactic Zone was the last ambitious park to be added in 2072.[4]

LEAP-X project

Main article: LEAP-X Program

With the overwhelming success surrounding his professional life, Bradberton garnered the attention of the United States military. Bradberton's Beverageers were some of the top organic chemists in the nation, prompting General C. Braxton of the Army Research Laboratory's Weapon and Material division to propose a contract with Bradberton in March 2076:[5] should Bradberton sign away his employees to work on chemical and biological weapons for Project Cobalt, he would be greatly compensated.[6]

With his influence in Washington, D.C., Bradberton was able to uncover information about a top-secret project: the LEAP-X Program (Life Extension And Prolongation). This project was dedicated to keeping humans alive indefinitely via a specialized machine; Bradberton knew that the world as he knew it was coming to an end soon, and with this project, Bradberton could live forever.[5][6]

General Braxton accepted the offer, and Bradberton put a team to work on the project immediately. Other than Bradberton and the Project LEAP-X team, Bradberton's executive assistant Peyton Huxley was the only one who knew about Bradberton's plans, and was trusted to handle his employer's affairs once he stepped out of the world's spotlight.[7][8]

Bradberton had originally thought the project involved the creation of a living bio-suit that would preserve the human body long after it would normally expire; however, much to Bradberton's frustration, the LEAP-X team informed him that because of how much power and how many special components the project required, no more than 15 pounds of organic material could be accommodated. This left him no choice but to have his head surgically removed to be preserved by the machines.[9] On April 2, 2077, Bradberton underwent the procedure to extend his life indefinitely, leaving the management of his affairs in the hands of executive assistant Peyton Huxley.[6][10][11]

Effects of player's actions

  • If his life support machine is switched off, his eyes will remain open and periodically move as if he's still alive.
  • If the player character accepts Sierra's offer and then shuts down Bradberton's life support machine, Sierra will condemn the Sole Survivor for their actions, furious for taking advantage of her, and then turns hostile. Should this happen, there are only two ways to proceed: kill Sierra or escape the bunker.


John-Caleb Bradberton appears in the Fallout 4 add-on Nuka-World. He is mentioned in Fallout 3 and the Fallout 76 update Wild Appalachia.[12]


  1. 1.0 1.1 World of Refreshment tour: "Nuka-Cola began its journey in the year 2042 when our founder, John-Caleb Bradberton, was a budding chemist. He dreamt of a delicious soft drink that would provide energy, focus and 120% of the recommended daily value of sugar!
    It took almost two years to perfect the formula, but in late 2044, Mr. Bradberton was finally successful and Nuka-Cola was born! It quickly surpassed other, lesser beverages to become America's number-one favorite soft drink. Not one to rest on his laurels, Mr. Bradberton and his team of talented "Beverageers" continued to create new and exciting formulas."

  3. Sierra Petrovita: "When Nuka-Cola was invented by John-Caleb Bradberton in 2044, it quickly became the world's most popular soft drink. The wonder drink soon drew a dedicated following which prompted the Nuka-Cola Corporation to release many promotional items like these. By 2067, a Nuka-Cola machine such as this rare pristine model could be found on almost every street in America. Even in today's crazy world, Nuka-Cola is still the number one choice of refreshment among Armageddon's survivors."
