Throughout occasions of political turmoil, historical past usually will get rewritten, erased, or misplaced. That’s what occurred to the legacy of Jan Czochralski, a Polish chemist whose contributions to semiconductor manufacturing have been expunged after World Warfare II.
In 1916 he invented a technique for rising single crystals of semiconductors, metals, and artificial gems. The method, now often called the Czochralski method, permits scientists to have extra management over a semiconductor’s high quality.
After the conflict ended, Czochralski was falsely accused by the Polish government of collaborating with the Germans and betraying his nation, in accordance with an article printed by the International Union of Crystallography. The allegation apparently ended his tutorial profession as a professor on the Warsaw University of Technology and led to the erasure of his identify and work from the college’s data.
He died in 1953 in obscurity in his hometown of Kcynia.
The Czochralski technique was honored in 2019 with an IEEE Milestone for enabling the growth of semiconductor gadgets and fashionable electronics. Administered by the IEEE History Center and supported by donors, the Milestone program acknowledges excellent technical developments around the globe.
Impressed by the IEEE recognition, Czochralski’s grandson Fred Schmidt and his great-grandnephew Sylwester Czochralski launched the JanCZ project. The initiative, which goals to coach the general public about Czochralski’s life and scientific affect, maintains two web sites—one in English and the opposite in Polish.
“Discovering the [IEEE Milestone] plaque modified my complete mission,” Schmidt says. “It impressed me to have interaction with Poland, my household historical past, and my grandfather’s story [on] a extra private stage. The [Milestone] is a vital award of validation and recognition. It’s a giant a part of what I’m constructing my complete case and my story round as I promote the Jan Czochralski legacy and historical past to the Western world.”
Schmidt, who lives in Texas, is searching for to supply a biopic, translate a Polish biography to English, and switch the chemist’s former properties in Kcynia and Warsaw into museums. The Jan Czochralski Remembrance Basis has been established by Schmidt to assist fund the initiatives.
The lifetime of the Polish chemist
Earlier than Czochralski’s delivery in 1885, Kcynia grew to become a part of the German Empire in 1871. Though his household recognized as Polish and spoke the language at dwelling, they couldn’t publicly acknowledge their tradition, Schmidt says.
When it got here time for Czochralski to go to school, relatively than attend one in Warsaw, he did what many Germans did on the time: He attended one in Berlin.
After graduating with a bachelor’s diploma in metallic chemistry in 1907 from the Königlich Technische Hochschule in Charlottenburg (now Technische Universität Berlin), he joined Allgemeine Elektricitäts-Gesellschaft in Berlin as an engineer.
Czochralski experimented with supplies to seek out new formulations that might enhance {the electrical} cables and equipment through the early electrical age, in accordance with a Material World article.
Whereas investigating the crystallization charges of metallic, Czochralski by accident dipped his pen right into a pot of molten tin as an alternative of an inkwell. A tin filament shaped on the pen’s tip—which he discovered attention-grabbing. By analysis, he proved that the filament was a single crystal. His discovery prompted him to experiment with the majority manufacturing of semiconductor crystals.
His paper on what he known as the Czochralski technique was printed in 1918 within the German chemistry journal Zeitschrift für Physikalische Chemie, however he by no means discovered an utility for it. (The tactic wasn’t used till 1948, when Bell Labs engineers Gordon Kidd Teal and J.B. Little tailored it to develop single germanium crystals for his or her semiconductor manufacturing, in accordance with Material World.)
Czochralski continued working in metallic science, founding and directing a analysis laboratory in 1917 at Metallgesellschaft in Frankfurt. In 1919 he was one of many founding members of the German Society for Metals Science, in Sankt Augustin. He served as its president till 1925.
Round that point he developed an innovation that led to his wealth and fame, Schmidt says. Referred to as “B-metal,” the metallic alloy was a cheaper various to the tin utilized in manufacturing railroad carriage bearings. Czochralski’s alloy was patented by the German railway Deutsche Bahn and performed a major function in advancing rail transport in Germany, Poland, the Soviet Union, the United Kingdom, and the United States, in accordance with Materials World.
“Launching this initiative has been fulfilling and personally rewarding work. My grandfather died in obscurity with out ever seeing the outcomes of his work, and my mom spent her complete grownup life making an attempt to proper these wrongs.”
The achievement introduced Czochralski many alternatives. In 1925 he grew to become president of the GDMB Society of Metallurgists and Miners, in Clausthal-Zellerfeld, Germany. Henry Ford invited Czochralski to go to his factories and supplied him the place of director at Ford’s new aluminum manufacturing unit in Detroit. Czochralski declined the supply, longing to return to Poland, Schmidt says. As a substitute, Czochralski left Germany to develop into a professor of metallurgy and metallic analysis on the Warsaw University of Technology, on the invitation of Polish President Ignacy Mościcki.
“Throughout World Warfare II, the Nazis took over his laboratories on the college,” Schmidt says. “He needed to cooperate with them or die. At night time, he and his crew [at the university] labored with the Polish resistance and the Polish Military to battle the Nazis.”
After the conflict ended, Czochralski was arrested in 1945 and charged with betraying Poland. Though he was capable of clear his identify, harm was executed. He left Warsaw and returned to Kcynia, the place he ran a small pharmaceutical business till he died in 1953, in accordance with the JanCZ undertaking.
Launching the JanCZ undertaking
Schmidt was born in Czochralski’s dwelling in Kcynia in 1955, two years after his grandfather’s demise. He was named Klemens Jan Borys Czochralski. He and his mom (Czochralski’s youngest daughter) emigrated in 1958 when Schmidt was 3 years previous, transferring to Detroit as refugees. When he was 13, he grew to become a U.S. citizen. He modified his identify to Fred Schmidt after his mom married his stepfather.
Schmidt heard tales about his grandfather from his mom his complete life, however he says that “as a youngster, I used to be simply considering hanging out with my pals, going to highschool, and dealing. I actually didn’t need a lot to do with it [family history], as a result of it appeared onerous to imagine.”

In 2013 Polish scientist Pawel E. Tomaszewski contacted Schmidt to interview him for a Polish TV documentary about his grandfather.
“He had corresponded with my mom [who’d died 20 years earlier] for beforehand printed biographies about Czochralski,” Schmidt says. “I had some packing containers of her issues that I began going by way of to arrange for the interview, and I discovered unique manuscripts and papers he [his grandfather] printed about his work.”
The TV crew traveled to america and interviewed him for the documentary, Schmidt says, including, “It was the primary time I’d ever needed to reckon with the Jan Czochralski story, my connection, my unique identify, and my birthplace. It was each a really cathartic and traumatic expertise for me.”
Ten years after taking part within the documentary, Schmidt says, he determined to reconnect along with his roots.
“It took me that lengthy to course of it [what he learned] and determine my function on this story,” he says. “That actually got here to life with my choice to reapply for Polish citizenship, reacquaint myself with the nation, and meet my household there.”
In 2024 he visited the Warsaw College of Know-how and noticed the IEEE Milestone plaque honoring his grandfather’s contribution to know-how.
“As soon as I discovered what the Milestone award represented, I assumed, Whoa, that’s massive,” he says.
Sharing the story with the Western world
Since 2023, Schmidt has devoted himself to publicizing his grandfather’s story, primarily within the West as a result of he doesn’t converse Polish. Sylwester Czochralski manages the work in Poland, with Schmidt’s enter.
Many of the out there writing about Czochralski is in Polish, Schmidt says, so his objective is to “unfold his story to English-speaking international locations.”
He goals to try this, he says, by way of a biography written by Tomaszewski in Polish that can be translated to English, and a movie. The film is in growth by Sywester Banaszkiewicz, who produced and directed the 2014 documentary in Poland. Schmidt says he hopes the film can be much like the 2023 biopic about J. Robert Oppenheimer, the theoretical physicist who helped develop the world’s first nuclear weapons throughout World Warfare II.
The English and Polish variations of the web site take guests by way of Czochralski’s life and his work. They spotlight media protection of the chemist, together with newspaper articles, movies, and informational movies posted by YouTube creators.
Schmidt is working with the Czochralski Research and Development Institute in Toruń, Poland, to buy his grandfather’s dwelling in Kcynia and the mansion he lived in whereas he was a professor in Warsaw. The institute is a set of labs and initiatives devoted to honoring the chemist’s work.
“It’s going to be a protracted, enjoyable journey, and we’ve got a whole lot of momentum,” Schmidt says of his plans to show the residences into museums.
“Launching this initiative has been fulfilling and personally rewarding work,” he says. “My grandfather died in obscurity with out ever seeing the outcomes of his work, and my mom spent her complete grownup life making an attempt to proper these wrongs.
“I’m on an accelerated course to make it [her goal] occur to the most effective of my potential.”
