Ferenc Krausz is a Hungarian physicist renowned for his pioneering work in the field of attosecond physics. Born on May 17, 1962, he is best known for developing techniques to generate and control attosecond laser pulses, which are significantly shorter than traditional laser pulses and allow scientists to observe and study ultrafast processes at the atomic and molecular levels.

György Jendrassik is primarily known as a Hungarian neurologist who made significant contributions to the field of neurology and clinical neurophysiology. He is particularly recognized for developing the Jendrassik maneuver, which is a technique used to facilitate the elicitation of the knee-jerk reflex (patellar reflex) by distracting the patient. This technique helps to heighten the reflex response, making it more pronounced during a neurological examination.
