Trask was a staff photographer for the Boston Evening Traveller when he photographed the Italian cruise ship SS Andrea Doria sinking into the Atlantic Ocean off the coast of Nantucket, Massachusetts. His pictures were widely published, including in Life magazine, and won him the 1957 Pulitzer Prize for Photography. Trask was using a 4×5 Speed Graphic camera from a light airplane. It is the second picture in the sequence, taken from a height of 75 feet, nineminutes before the ship sank, that won the Pulitzer Prize. His sequence continues to show the ship sinking.
