Harry Zvi Tabor (7 March 1917 – 15 December 2015) was a British-born scientist who became a leading figure in the development of practical solar thermal technology in Israel and beyond. Born in London, he emigrated to the area that became Israel and spent much of his career combining laboratory research with field engineering to make solar energy systems more efficient, durable and affordable. As a physicist he worked on materials and designs that improved heat collection and retention, and he is often described as a founder of the modern Israeli effort in solar energy.
Research and technical contributions
Tabor's technical work addressed several practical limitations of early solar collectors. He investigated selective surface coatings that increase absorption of sunlight while reducing thermal emission, improvements in insulation and glazing, and the use of evacuated or insulated elements to cut convective losses. These areas of research directly influenced the performance of domestic solar water heaters and small industrial collectors by raising achievable temperatures and improving year-round efficiency. His emphasis on low-cost manufacturing and robustness helped shift solar thermal technology from experimental prototypes to widely used systems.
Career and practical impact
Throughout his career he collaborated with research organizations, manufacturers and government agencies to adapt laboratory results to products and public programs. Tabor promoted demonstration projects, training for technicians and engineers, and standards that helped ensure reliability in everyday installations. His outreach contributed to wider acceptance of solar water heating and to the integration of solar thermal ideas into national policy. That combination of science, engineering and advocacy brought attention to Israeli solar energy developments internationally.
Publications, patents and teaching
In addition to laboratory studies and engineering reports, Tabor published articles aimed at both specialist and applied audiences and participated in conferences that promoted international exchange of methods and lessons learned. He worked to translate research findings into patented or licensed technologies and to advise firms that produced collectors and coatings. Through teaching and mentorship, he influenced several generations of engineers and scientists involved in renewable energy.
Legacy
Often referred to as the father of Israeli solar energy, Tabor's legacy rests on combining rigorous study of materials and heat transfer with an insistence on practical, manufacturable solutions. The technologies he advanced—selective absorber coatings, improved glazing and insulation, and simplified durable collector designs—remain central elements in many solar thermal systems. He helped place Israeli innovations on the international map and encouraged the broader adoption of solar thermal heating as a cost-effective renewable resource. Tabor died in Jerusalem on 15 December 2015 at the age of 98.
