This travel book tells the true story of how, in 1997, writer Michael Paterniti agreed to take a road trip from New Jersey to California, reuniting the preserved brain of the great scientist Albert Einstein (1879-1955) with his granddaughter Evelyn. Paterniti's travelling companion is 84-year-old Thomas Harvey, the pathologist who not only removed Einstein's brain from his head during the autopsy but also purloined it from Princeton Hospital. Storing the great scientist's brain in a Tupperware zipped inside a grey duffel-bag, they rent a Buick Skylark, and drive from New Jersey to Ohio, Kansas City to Dodge City, Los Alamos to Las Vegas, finally achieving their bizarre reunion in Berkeley, California.
