Sigmund Freud vs Max Planck
Yes — based on their recorded years, Sigmund Freud (1856–1939) and Max Planck (1858–1947) were alive at the same time for at least part of their lives.

Freud fled Vienna for London in 1938 after the Nazi annexation of Austria, having to pay a substantial 'exit tax' to the Nazi regime and leave behind much of his property to secure his family's escape.
Full profile of Sigmund Freud →Max Planck
Max Planck was a German theoretical physicist whose discovery of energy quanta in 1900 launched the field of quantum physics, earning him the 1918 Nobel Prize in Physics.
Key achievements
- Discovered that energy is emitted and absorbed in discrete units, or quanta, in 1900.
- Won the 1918 Nobel Prize in Physics for his discovery of energy quanta.
- Laid the foundational groundwork for the field of quantum mechanics.
- Served as a leading figure in German physics institutions for decades.
Fast fact
Planck's 1900 discovery of quantized energy, originally intended to solve a specific problem in thermal radiation, unexpectedly launched the field of quantum mechanics that would revolutionize physics in the following decades.
