Francis P. Hammerberg
United States Navy Medal of Honor recipient (1920–1945)

Owen Francis Patrick Hammerberg (May 31, 1920 – February 17, 1945) was a United States Navy diver who received the Medal of Honor posthumously for rescuing two fellow divers.
Biography
Hammerberg was born at Daggett, Michigan, on May 31, 1920; his family subsequently moved to Flint when he was young.
He enlisted in the United States Navy June 16, 1941 and subsequently served on battleship USS Idaho (BB-42) and mine sweeper USS Advent (AM-83). Later that year, he underwent instruction at the Deep Sea Diving School, Washington, D.C., and was assigned duty with the Mobile Diving Salvage Unit under Service Force, Pacific Fleet.
During salvage in the aftermath of the West Loch Disaster, he lost his life in a rescue operation at Pearl Harbor on February 17, 1945. Disregarding all personal danger, he rescued one diver who had been trapped in a cave-in of steel wreckage while tunneling under a sunken LST. After this rescue, Hammerberg went even farther under the buried hulk and, while rescuing a second diver, was pinned down by another cave-in and perished. Boatswain's Mate Hammerberg posthumously received the Medal of Honor; he is the last person to be awarded the medal for non-combat heroism.
He was buried at Holy Sepulchre Cemetery in Southfield, Michigan.
Namesake
In 1955, the destroyer escort USS Hammerberg (DE-1015) was named for him. A street in Flint and a playing field in Detroit are also named Hammerberg in his honor.

Why this record matters
The subject matters to the general reference register because the source frames it as united States Navy Medal of Honor recipient (1920–1945). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q5482118. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1920, 1945, 1941 and 1955.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
