Joseph R. Fisher was born on March 14, 1921, in Allston, Massachusetts. He was raised in Westwood and graduated from Dedham High School. Fisher enlisted in the Marine Corps in 1942 and quickly rose to the rank of platoon sergeant. By February 1945, Platoon Sergeant Fisher was assigned to Company C, 1st Battalion, 26th Marines, 5th Marine Division. On the afternoon of February 19, Fisher's battalion made an amphibious landing at Red Beach 1 on Iwo Jima. On the morning ofFebruary 21, while his battalion assaulted Airfield No. 1 Fisher's company became pinned down by a Japanese machine gun bunker. Fisher began crawling toward the machine gun with several hand grenades when he was shot through his shoulder and then his chest in quick succession. Despite his wounds, Fisher crawled the rest of the way to the bunker and silenced the position with his grenades. He then refused to be evacuated and continued leading his platoon before he lost consciousness. Fisher was awarded his first Silver Star for his actions. He spent several months in a hospital and returned to duty in July 1945. Fisher was then commissioned as a second lieutenant and took part in the occupation of Japan.
When the Korean War broke out, First Lieutenant Fisher was given command of Company I, 3rd Battalion, 1st Marines, 1st Marine Division. Fisher was personally appointed as a company commander by his regiment commander, ColonelChesty Puller, who remarked that Fisher was "one of the best damned company commanders who ever lived." Fisher led his company during the amphibious assault at Inchon and the subsequent recapture of Seoul in September 1950. Outside the city of Seoul, his company defended Hill 105S from a North Korean attack and captured 10 prisoners. During the entire Inchon-Seoul campaign, Fisher lost only one Marine killed and two wounded. At the conclusion of the campaign, the entire 1st Marine Division embarked on Navy ships which sailed around South Korea and landed at Wonsan in October. The division then marched 70 miles north to the Chosin Reservoir area. As the Marines arrived at Chosin Reservoir, the Chinese Communist military encircled the entire division and the coldest winter in 50 years descended on Korea. Temperatures fell as low as −35 °F as a blizzard swept the area. On November 25, First Lieutenant Fisher positioned his company on "East Hill" which strategically overlooked the village of Hagaru-ri. At 10:30 p.m. on November 28, Company I was attacked by a Chinese regiment. Fisher repeatedly exposed himself to the heavy fire to direct mortar fire, direct the fire of his Marines and increase morale. At one point during the night, the Chinese penetrated the perimeter of 3rd Platoon and Fisher led a counterattack and engaged in hand-to-hand combat. The battle lasted for eight hours, concluding on the morning of the 29th. After three failed attempts to take the hill, the Chinese withdrew, leaving approximately 700 of their dead who had been killed during the battle. When Colonel Puller asked Fisher how many of the enemy he had killed, Fisher replied, "A whole piss pot full, sir." Puller later evaluated Fisher to be the best company commander in the Marine Corps. For his actions during the battle of Chosin Reservoir, Fisher was awarded the Navy Cross; Puller was awarded his 5th Navy Cross.
In May 1965, 2/4 was reassigned to the 3rd Marine Division and deployed to Vietnam, arriving at Chu Lai. On August 18, 1965, Lieutenant Colonel Fisher led his battalion in a helicopter assault near Van Tuong, commencing Operation Starlite. Fisher led his Marines during four days of continuous combat with very little sleep. By August 24, Lieutenant Colonel Fisher’s battalion had killed more than 300 of the enemy. For his actions during Operation Starlite, Fisher was awarded his second Silver Star.
