David Kestenbaum

David Kestenbaum is a correspondent for NPR, covering science, energy issues and, most recently, the global economy for NPR's multimedia project Planet Money. David has been a science correspondent for NPR since 1999. He came to journalism the usual way — by getting a Ph.D. in physics first.

In his years at NPR, David has covered science's discoveries and its darker side, including the Northeast blackout, the anthrax attacks and the collapse of the New Orleans levees. He has also reported on energy issues, particularly nuclear and climate change.

David has won awards from the American Association for the Advancement of Science, the American Physical Society and the Institute of Electrical and Electronics Engineers.

David worked briefly on the show This American Life, and set up a radio journalism program in Cambodia on a Fulbright fellowship. He also teaches a journalism class at Johns Hopkins University.

David holds a bachelor's of science degree in physics from Yale University and a doctorate in physics from Harvard University.

The Birth Of The Minimum Wage In America

Originally published on Fri January 17, 2014 3:46 pm

In 1895, legislators in New York state decided to improve working conditions in what at the time could be a deadly profession: baking bread.

"Bakeries are actually extremely dangerous places to work," says Eric Rauchway, a historian at the University of California, Davis. "Because flour is such a fine particulate, if it gets to hang in the air it can catch fire and the whole room can go up in a sheet of flame."

This famous bet — between a biologist and an economist — was over population growth. It started three decades ago, but it helped set the tone for environmental debates that are still happening today.

The biologist at the heart of this bet was Paul Ehrlich at Stanford. He wrote a best-selling book in 1968 called The Population Bomb. It was so popular he appeared on The Tonight Show with Johnny Carson.

Jake Malta left his job as chief engineer at Schulmerich, the world's biggest handbell company, in 1973.

But Malta couldn't stop thinking about bells. He had a vision for a perfect bell — a bell he had never quite achieved at Schulmerich.

So he set up shop in his living room. "He had a folding table, two of them, stretched out with all of his drafting supplies and piano behind him," his daughter, Joann, says.

He traveled to Europe and studied the physics of bells. He made sketch after sketch. "He knew that he could make it better," his daughter says.

Meet The Humble Container That Moves The Global Economy

NPR's Planet Money team is manufacturing its own T-shirt. After the women's shirt was assembled in Colombia, they voyaged by container ship to Miami. The container, a big standardized box that moves easily from truck to ship to train, is the unsung hero of the global economy. It was invented in the 1950s and dramatically reduced shipping costs, ushering in a new era vastly different than the world retired stevedores remember.
