David Bradley, an Atlanta carpenter and writer, and also a high school dropout, won for a second time on “Jeopardy!” Monday night.

Clad in a pale green shirt and black bow tie, Bradley, the returning champion beat a pathologist and graduate student.

He won $28,000, bringing his total winnings to $55,000.

Early in the game, Bradley was far behind. Even Jeopardy host Alex Trebek said Bradley and the other competitor had a lot of catching up to do the pathologist, who was leading by several thousand of dollars.

He started making a comeback and then betting $4,000 in a Daily Double about Jack London (He sought his fortune in yukon gold prospecting, but made it big as the USA’s highest-paid writer) catapaulted Bradley into the lead.

The final Jeopardy clue was about world leaders: In 2006 a former llama herder became president of this country.

He answered correctly Bolivia.

On Friday night, Bradley outscored an emergency room physician and a naval officer.

Bradley returns Tuesday (7:30 p.m. WXIA-TV NBC) for another round of competition.

Competing on “Jeopardy!” was a lifelong dream for Bradley, who has taken an unlikely path to earn a coveted spot in the popular and highly competitive quiz show. Bradley, 55, is a high school dropout. He was kicked out of high school for skipping too many classes. His senior year GPA was 1.6.

On Friday night, Bradley continued to do well in the quiz show, where all of the answers come in the form of a question. He didn’t hesitate when Vice President Joe Biden himself (via video) provided a clue about portraits in his office in the West Wing featuring the country’s first two vice presidents. Bradley pressed the buzzer: “John Adams and Thomas Jefferson.”

Although Bradley cannot reveal how he does in future shows, he said in a recent interview the experience gave him an even deeper appreciation for the game show.

“The experience left me with such respect for the crew, the other contestants who were all so wickedly smart,” he said. “I watch it now with increased respect.”

Bradley, who is working on a documenatry about old-time fiddling, is also demonstrating just how much knowledge a person can acquire even if one doesn’t follow a traditional path of going to school.

Although he was uninterested in school as a teenager, he always had a thirst for knowledge and a love for reading. After high school, he worked in construction, and for several years, he worked hanging Sheetrock. All the while, he frequented yard sales and thrift stores, buying books on a variety of subjects. Many, he said, turned out to be college textbooks — science, history, physics. He read them all.

He also watched “Jeopardy!” almost every weeknight, answering the questions with ease.

By the time Bradley was in his 40s, he found himself getting laid off repeatedly. He decided it was time to carve out a new profession. At age 45, he started going to college. He graduated from Georgia State University when he was 50. Inspired by a history class during his senior year, he wrote the book, "Martyrs of Guale: An Addison Kane History-Mystery" which is available on Amazon.

He also enjoyed meeting Trebek, the host of the show in its 32nd season in syndication, with 25 million viewers each

week.

“Alex is as warm and genuine and funny and human as you wished he would be,” he said.
