At its peak, the Manhattan Project had around 130,000 people working on it, including some of the most prominent scientists of the time. You had guys like J. Robert Oppenheimer, Enrico Fermi, and Ernest Lawrence, all working together to figure out how to harness the power of the atom. It's like a dream team of scientists, all working towards a common goal.
But it wasn't just the big-name scientists who made the project happen. There were thousands of other researchers, engineers, and technicians who worked tirelessly behind the scenes to develop the bomb. These people were the unsung heroes of the project, and without them, it would never have been completed. It's amazing to think about how many dedicated individuals were involved in this project.
The project was so secretive that many of the people working on it didn't even know what they were working on. They were just told to build a certain part or conduct a certain experiment, without being given any context. It's like a big puzzle, with each person playing a small part in the overall picture.
