World War II
Degaussing at Castle Island During World War II Castle Island was chosen for a special naval project. In a process called “Degaussing,” named after the German scientist Carl Freidrich Gausse, electric coils were wrapped around ship’s hulls to reduce magnetic attraction for mines. In the Castle Island version, called “wiping,” ships passed over coils buried in the harbor for temporary demagnetizing

From Castle Island to Oahu
After Charles Lindberg’s historic flight, James Dole of the pineapple company offered a prize for the first flight from the mainland to Hawaii. Army aviators Lester J. Maitland and Albert F. Hegenberger made the flight from Oakland, California in twenty-five hours and fifty minutes. Seven others lost their lives in the attempt.

In 1919 Lieutenant Hegenberger married Louise Berchtold in the “only wedding ceremony” ever held on Castle Island. Louise’s family lived on the island in a caretaking role. Hegenberger grew up in South Boston, attended MIT, and joined the army air corps, combining technical and flying skills. 

Into the Twentieth Century
In 1890 the city of Boston received permission to improve and beautify (but not own) the island. By 1892 a wooden bridge connected Castle Island to the mainland. In 1932 a causeway opened on land filled with mud, clay and silt. Many modern visitors don’t realize that the site was originally an island.

Frederick Law Olmsted proposed creating an Emerald Necklace of green space around metropolitan Boston. Castle Island would be included. Seeing military value in Fort Independence, the federal government hesitated.
