János Neumann (1903-1957)

Most likely, you use a computer on a daily basis for work, or you have activities that require computational systems. Computers are everywhere: we use them for shopping, reading the news, sending messages, medical research, economic planning, watching movies, and playing games. Did you know that János Neumann, also known as John von Neumann, who came from a Jewish family from Marghita, made significant contributions to the development of modern informatics systems?

János Neumann was born in 1903, when his family, who was culturally assimilated and non-observant, had been long settled in Budapest. His father, a bank director, could provide him with the best education: he learned foreign languages, attended an elite high school, and met university professors who discovered his talent and encouraged him to develop it at a young age. He studied mathematics, physics, and chemistry in Budapest, Berlin, and Zürich.

Childhood portrait. János Neumann's talent for mathematics was remarkable already at a very young age.

He was invited to Princeton University in 1930, where he taught and worked on cutting-edge research projects. During WWII, he was involved in the development of the atomic bomb, which led to his profound ethical quandaries about science. Together with Oskar Morgenstern, he generated game theory, which can be used to understand decision making in economics, politics, and armed conflicts.

János Neumann played a critical role in developing digital computers by employing the binary numeral system and developing the structures required for storing data and programs, which sparked the 1950s-1960s informatics revolution. Our world would most likely be very different if he and his colleagues did not exist.

János Neumann's daughter, Marina, wrote a captivating memoir about their family.

Orsolya András graduated from the Faculty of Letters, Babeș-Bolyai University, Cluj. Since 2012 she works as a freelance translator and currently is museum assistant at Muzeon.

Donate for Muzeon


Muzeon has become a Transylvanian landmark for Jewish culture. Despite the fact that we opened during the pandemic, we had over 4,000 visitors. However, the crisis has deepened, and the operational expenditures can no longer be covered. The harsh reality is that the museum is on the verge of closure.

With your help, Muzeon can continue to stay open! Please sign up to make a monthly donation to the museum. That will enable us to provide you with the highest quality of information that you expect from us and, also, to keep the Jewish heritage alive as well as to ensure the remembrance of the Holocaust. Muzeon started as an independent museum. It receives no public funding. During these difficult times, with tourism reduced to a trickle by the pandemic, we can no longer afford the cost of keeping the museum open.

Now is the time to chip in for the preservation of Jewish heritage and Holocaust memory in Transylvania. With just 10 euros per month from 100 people, this museum will be able to continue to operate.
