Jerome Daniel “Jitters” Moderski was born at Milwaukee, Milwaukee County, Wisconsin on December 7, 1920. He was called 'Jitters' because he loved to dance. He was the only child of Stanley Louis Moderski (14 Apr 1893 – 23 Feb 1961) and Pelagia 'Pearl' (Latus) Moderski (10 Mar 1893 – 2 May 1975), who were born in Wisconsin. His parents married about 1919. His grandparents were all born in Poland. By 1935 the family lived at 2807 South 45th Street, Milwaukee, Wisconsin. His father was a foreman for an express transportation company in Milwaukee.

He completed four years of high school, and registered for the draft at Milwaukee, Wisconsin on February 14, 1942. He was 5 feet 7 inches tall, weighed 155 pounds, and had blue eyes and brown hair. He worked as a checker and was single, without dependents, when he enlisted in the U.S. Army Air Corps at Milwaukee, Wisconsin on September 14, 1942. He married Marjorie E. Hamann (22 Sep 1922 – 1 Jun 2014) at Alamogordo, New Mexico in January 1944. In 1945 his wife lived at 3525 North 38th Street, Milwaukee, Wisconsin.

He completed Army Air Forces bombardier training in Class 43-13 at Big Spring, Texas, and was commissioned a Second Lieutenant on September 16, 1943. He was then assigned to the heavy bomber crew of Lt Loye James 'Jack' Lauraine Jr in the 837th Bomb Squadron, 487th Bomb Group, at Alamogordo Army Air Base, New Mexico. There they completed B-24 crew training, and deployed with the Group to England in March 1944. They flew B-24H 42-52425 'The Tweachewous Wabbit' overseas via the southern Atlantic ferry route—a journey of about 10,000 miles—and arrived in England by mid-April 1944. The 487th Bomb Group was based at Army Air Forces Station 137 near Lavenham, Suffolk, England, and was part of the 8th U.S. Army Air Force in Europe.

Lt Moderski completed his first combat tour with the Lauraine crew. During that time, the 487th Bomb Group transitioned from the B-24 'Liberator' to the B-17 'Flying Fortress'. He returned to the United States for leave, and returned to Lavenham for a second combat tour. He was reassigned to the crew of Lt Lauraine, who had also returned for a second tour. Lt Thomas Hafner, the crew's original navigator, also rejoined the crew.

On November 25, 1944, the 487th Bomb Group dispatched three squadrons of B-17s to bomb the large I. G. Farben synthetic oil refinery at Leuna near Merseburg, Germany. The Lauraine crew flew B-17G 42-97997 'Honorable Patches' on this mission. The aircraft sustained severe flak damage on return from the mission, and some control cables were shot away. Lt Lauraine was able to pilot the aircraft across the English Channel, but was unable to land. Lt Moderski and the other crew members bailed out just north of Ipswich, England and survived. Lt Lauraine stayed at the controls to prevent the aircraft from crashing on the base of the 390th Bomb Group at Framlingham. The aircraft then went into a spin and crashed two miles east of the base on Arthur Latter's farm. Lt Lauraine was unable to bail out, and died in the crash.

On March 15, 1945, Lt Moderski flew as bombardier on the lead crew of Lt Joseph D. Conwill Jr in the 837th Bomb Squadron. The mission was to bomb the railroad marshalling yards at Oranienburg, Germany. Lt Conwill's crew lead the Diamond Squadron (aka Low, Low Squadron) of the 487th Bomb Group formation. Air leader Captain Robert G. Reeder flew in the copilot seat. Copilot Lt Birtrum Lindquist moved to the tail gunner position as officer tail gunner and formation observer, as was the custom.

Lt Moderski and three of his crewmates were killed in action when their aircraft, B-17G 44-8746, was shot down by flak over Wittenberge, Germany in the Elbe River Valley. They had dropped their bombs on the marshalling yards at Oranienburg, and encountered intense, accurate flak over Wittenberge on the return. Direct flak hits blew off the nose of the aircraft and the forward underside of the fuselage.

The remains of navigator Lt McNeish were found in a German churchyard in 1947. This was probably at Perleberg, Germany, a short distance northeast of Wittenberge. Lt Moderski's remains may have been found there about the same time. His remains were permanently reinterred at Ardennes American Cemetery, Belgium.
