William Warin Bainbridge Jr., Class of 1922, and Kenneth Tompkins Bainbridge, Class of 1926, grew up on Manhattan’s Riverside Drive, the eldest of three sons of an upwardly cell stationer who dabbled in actual property. Each went to MIT. And each would play essential roles in World Warfare II—one on the entrance strains at Normandy and on the Battle of the Bulge, the opposite with J. Robert Oppenheimer in Los Alamos.
Earlier than making their method to MIT, the brothers attended the Horace Mann Faculty, the place they participated in athletics and Ken wrote for the newspaper and the humor journal. However whereas Invoice was enjoying hockey, Ken was busy exploring the brand new medium of radio. “I had a radio with an antenna on the roof [of the family townhouse],” he recalled in 1991. “The antenna and floor had been linked throughout the vibrating contacts, which energized a industrial ultraviolet unit. I should have violated each bandwidth legislation.” Ken’s five-watt ham radio station had simply three name letters: 2WN.
In 1918, Invoice arrived on the Institute, the place he majored in engineering administration. He belonged to a dizzying variety of organizations, together with two fraternities (Alpha Tau Omega and Theta Tau), the soccer workforce, the wrestling workforce (which he managed), and the finance and funds committees. Ken joined Invoice at MIT within the fall of 1921 to check electrical engineering, in the end incomes each a bachelor’s and a grasp’s diploma by a co-op program with Basic Electrical that required him to spend time at GE’s workplaces in Lynn, Massachusetts, and summers on the GE campus in Schenectady, New York. Ken, too, pledged Alpha Tau Omega, and he served on the board of MIT’s Voo Doo humor journal. Grasp’s in hand, Ken and an MIT good friend had been admitted in 1926 to the doctoral program in physics at Princeton, the place the dean reportedly advised them, “You’re good boys, nevertheless it’s too dangerous you by no means went to varsity.”
Regardless of the dean’s skepticism, Ken rose rapidly within the educational ranks—first at Princeton, the place he grew to become a pioneering mass spectroscopist; then at Cambridge College’s Cavendish Labs on a Guggenheim fellowship; after which at Harvard, the place he constructed cyclotrons. Alongside the best way, he printed the outcomes of an experiment confirming Einstein’s most well-known equation, E = MC2. He returned to MIT in 1940 to assist discovered the Radiation Laboratory and performed a key position in recruiting scientists and growing radar.
However on September 22, 1943, a letter to the native Warfare Workplace from President Karl Taylor Compton famous that Bainbridge was unavailable for brand new native work as a result of his “companies had been urgently requested by one other scientific venture of maximum urgency and secrecy.” Since MIT couldn’t refuse, Compton wrote that “Bainbridge was launched from the Radiation Laboratory to take part on this new exercise.”
The “exercise” was “Undertaking Y” at Los Alamos Nationwide Laboratory, the place Ken and his cyclotron helped develop the primary nuclear bomb.
Ken settled at Los Alamos together with his spouse, Margaret, previously a member of the Swarthmore Faculty college, and their three youngsters. Beneath Oppenheimer’s path, he took cost of the Initiator Committee and joined the “high-explosives” group. Then he was given the big accountability of main the trouble to check the atomic bomb, which required working by numerous technical and theoretical challenges. He was named head of Group E-9, “to check full-scale implosion assemblies and put together for the Trinity check,” and Group E-2, which developed instrumentation for the check. In October 1944, Ken grew to become a member of the detonator committee.
The opposite members of the Bainbridge household additionally threw themselves into the struggle effort. Mae, the matriarch, volunteered for the American Pink Cross. Youngest brother Don, a Cornell grad, grew to become a lieutenant within the Military Corps of Engineers. Invoice, who’d been working in building for US Gypsum, was commissioned at age 39 as a primary lieutenant of the 342nd Engineers (he’d served beforehand as a second lieutenant early in his profession). He headed to the UK in 1942 to turn out to be a regimental operations officer, utilizing his constructing expertise to oversee highway stabilization and work that required using heavy earthmoving machines. By yr’s finish he’d been promoted to captain, and in 1943 he was transferred to the 254th Engineer Fight Battalion, V Corps.
As an assistant division engineer, Invoice spent the primary half of 1944 coaching for the Normandy invasion. At 7:40 a.m. on June 6, 1944, his battalion landed at Omaha Seaside. Invoice, who was barely wounded, and 4 different troopers “made engineering reconnaissance from behind German strains,” as he would later describe it, to look at German engineering infrastructure. Then they captured 5 German troopers and rejoined the remaining members of their battalion on the seashore, the place they breached the wall blocking the seashore exit with 1,100 kilos of TNT. For his actions on D-Day, Invoice obtained a Purple Coronary heart and a Silver Star. He later wrote that on June 8, his battalion “made reconnaissance of a spot in [a] bridge over Vire River, underneath German commentary and fireplace”; they later bridged the hole.
One of many first battalions to enter Paris, the 254th went on to construct a number of bridges, take away obstacles and mines, preserve roads, and help stalled infantry and armor items because the Allies made their manner throughout France. On September 11, 1944, it was one of many first battalions to achieve Germany, the place it could destroy 52 fortified positions.
Seven months after D-Day, Invoice Bainbridge’s frivolously armed battalion helped cease the German panzer divisions within the Ardennes Offensive, higher generally known as Battle of the Bulge, for which the lads would earn the Croix de Guerre. On December 17 they withstood two assaults, and managed to stop supporting German infantry from advancing after a 3rd assault with tanks breached their strains. They held off the Germans for 9 hours till aid arrived. Reportedly, the annoyed SS commander was heard to mutter, “The damned engineers!”
Ken Bainbridge famously turned to Oppenheimer after the blast and mentioned, “Now we’re all sons of bitches.”
“Our battalion was minimize off and fought its manner into after which out of the German strains to flee … scattered over a 40-mile entrance,” Invoice wrote. They might go on to cross the Rhine River, the place they constructed a 330-foot floating bridge, the biggest tactical bridge within the European theater—preventing Nazi troops all the best way.
Injured through the preventing, Invoice was hospitalized in France for almost a month. Throughout that point he met his wife-to-be, Captain Florence Thompson, a nurse from Nova Scotia beforehand stationed at Boston’s Robert Brigham Hospital. Their marriage ceremony announcement within the New York Instances might solely report that they married in February 1945 “someplace in France.”
From Might to October of 1945, Invoice labored on his ultimate project of the struggle: designing and supervising the development of 18 French camps. These camps, he wrote, needed to accommodate “480,000 males who had been to return from Germany and put together for the invasion of Japan.”
That full-out invasion of Japan grew to become pointless, in fact, due to his brother and his Los Alamos colleagues. As Invoice was designing the camps, Ken was selecting the positioning for the primary atomic detonation—a spot within the New Mexico desert referred to as the Jornada del Muerto, or “Journey of the Useless Man.”
The world’s first atomic bomb exploded at 5:29:45 a.m. Mountain Warfare Time on July 16, 1945, lower than a month earlier than the bombing of Hiroshima and Nagasaki. Ken, who would later name it a “foul and superior show,” famously turned to Oppenheimer after the blast and mentioned, “Now we’re all sons of bitches.”
After the struggle, Ken returned to the Harvard physics college, the place he later grew to become division chair. He would additionally turn out to be a distinguished advocate of accountable nuclear energy and defend educational freedom towards Senator Joseph McCarthy. He retired from Harvard in 1975 however remained energetic professionally till his loss of life in 1996.
In the meantime, Invoice, who had earned the rank of main, returned to civilian life as a constructing part engineer, developer, and inventor, in response to David A. Bainbridge, the son of Invoice and Ken’s cousin and writer of Sport Changer: World Warfare II, Radar, the Atomic Bomb, and the Lifetime of Kenneth Tompkins Bainbridge. Whereas for Ken the struggle years might have been “his finest time,” David says, Ken’s daughter suspects that Invoice might need been affected by PTSD.
Even within the midst of struggle, Invoice was nonetheless pondering of MIT. From France, he despatched a Nazi flag captured from the headquarters of a German panzer battalion to President Compton. “Some months in the past,” Compton wrote to Invoice in 1945, “we obtained the big Nazi flag and the small embroidered identification quantity, which evidently signify some captured trophies and which have elicited a lot curiosity as I’ve proven them to guests in my workplace.” Invoice wrote again, a little bit insouciantly: “Pricey Dr. Compton: Was most agreeably shocked to listen to from you and enormously loved your letter. I’m afraid it’s fairly late to start out a German trophy assortment though within the years to return undoubtedly our wives will make us eliminate stuff now we have despatched residence.”
Ken would additionally make a present of kinds to MIT when growing plans for a joint Harvard-MIT cyclotron. “Harvard didn’t care whether or not it was positioned at MIT or Harvard. MIT didn’t care whether or not it was Harvard or MIT,” he mentioned in 1977. “You simply didn’t need midway in between in Central Sq., being equally inconvenient to all people.” So Ken determined to make life extra handy for the scientists of his alma mater, and the cyclotron ended up in Constructing 44.
“Each the Bainbridge brothers actually benefited from their MIT time,” says David Bainbridge. “They had been arrange completely for the roles they had been going to play in World Warfare II.” And in very other ways, the 2 brothers’ contributions helped convey concerning the finish of the struggle.
