David Hahn was born in Royal Oak, Michigan. While details about his early childhood are scarce, it's known that he developed an early interest in science and chemistry, fueled by chemistry sets and a natural curiosity about the world around him.

During his adolescence, Hahn's fascination with chemistry and science intensified. He immersed himself in textbooks, conducted experiments, and became increasingly driven to understand complex scientific concepts. This period marked the genesis of his later nuclear ambitions.

Hahn joined the Boy Scouts of America, a decision that would significantly shape his project. He pursued merit badges with great enthusiasm, eventually earning the Eagle Scout rank, although some controversy surrounded his Nuclear Science merit badge due to his unconventional approach to gaining knowledge.

Driven by a desire to create a breeder reactor, Hahn began his increasingly ambitious project. He scoured for radioactive materials, collecting small amounts from household products like smoke detectors (americium), lantern mantles (thorium), and even attempted to extract radium from antique clocks. He diligently researched nuclear processes and the construction of reactors, often corresponding with experts under false pretenses.

Growing concerned about the health risks and potential dangers, Hahn's mother and neighbors alerted the authorities after Hahn’s car was stopped by police and found to contain radioactive materials. The EPA declared Hahn's mother's property a Superfund site and disassembled the makeshift reactor. Hahn was never charged with a crime.

The story of the "Radioactive Boy Scout" gained national attention, with articles appearing in major news outlets. This brought Hahn's story to a wider audience, raising concerns about the accessibility of radioactive materials and the potential for individuals to undertake dangerous scientific experiments without proper oversight.

After the incident, Hahn joined the Navy and served for several years. However, he continued to struggle with mental health issues and substance abuse. His life was marked by challenges in adapting to normalcy after his early notoriety and the fallout from his experiment.

David Hahn passed away on September 27, 2016, at the age of 39. His death was attributed to alcohol, drug and fatty degeneration of the liver. His story remains a prominent example in discussions about scientific curiosity, responsibility, and the potential consequences of unchecked ambition.
