Ludovit Kubicar is well known for his active role in the field of thermal conductivity. He was the lead developer of the transient technique to measure specific heat, thermal conductivity and thermal diffusivity of materials, and co-authored the patents for the pulse method that measures thermophysical parameters, as well as the hot-ball method that measures thermal conductivity. Kubicar’s journey into the world of thermal conductivity began when he attended the Technical University of Bratislava, where he studied Solid State Physics for the Faculty of Electrotechnical Engineering and graduated in 1963. Kubicar then went on to the Institute of Physics at the Slovak Academy of Sciences in Bratislava, where he earned his PhD in Solid State Physics in 1970 and his DSc in Measurement techniques of thermophysical properties in 1990. Additionally, he participated in multiple studies at prestigious institutes including the National Physical Laboratory in the UK, the University of California at Santa Barbara, the National Institute of Advanced Industrial Science and Technology in Japan, and The National Metrology Institute of Germany. From 1997-1999, Dr. Ludovit Kubicar took on the role of symposium coordinator at the Institute of Physics of the Slovak Academy of Sciences in Bratislava. In 2000, he received the “INCHEBA 2000” award at the 32nd International Chemical Fair in Bratislava for his Thermophysical Transient Tester RT 1.02. The following year, Kubicar accepted the “Thermal Conductivity Award” at the 26th International Thermal Conductivity Conference and the 14th International Thermal Expansion Symposium in Cambridge, MA, for that same work. Due to his lifelong dedication and contributions to the scientific community, Dr. Ludovit Kubicar is regarded as one of the founding fathers of modern thermal conductivity.
