Olga Owens Huckins watched the birds falling lifeless all around her property in Massachusetts in January 1958. It was just after the area had been sprayed with DDT from a plane.

Carson was a marine biologist and a best-selling nature writer who was already very concerned about the use of man-made chemicals, especially pesticides, on the natural world.

Carson already had three best-selling non-fiction books: Under the Sea Wind, The Sea Around Us and The Edge of the Sea. She added her friend’s letter to the evidence she was building for her next book.

Sketch of Ada Bryon at 17

On 5 June 1833, Ada Bryon attended a party at mathematician Charles Babbage’s house. She’d been presented at court a few days earlier so it was simply part of the London season. Except Babbage invited Ada to see his prototype Difference Engine. It was the start of an intellectual friendship that resulted in Ada becoming the first theoretical computer programmer.
