Personal life[ edit ] He was born in Tel Aviv, Israel and sent to an English boarding school at the age of 7. After completing his secondary education he returned to Israel to carry out his military service before moving back to England to study physics at Cambridge University. He received his Ph. His work is applicable to a wide range of industrial and fundamental science problems.

He devised world-leading experimental methods to measure the physical forces acting between surfaces in close proximity. These surface forces determine the behaviour of a collection of particles or objects, and they are important in many areas of nanotechnology, colloid science, tribology, biophysics and materials science.
A kind, witty and charismatic person, he won the respect and the affection of his many students, postdocs and colleagues over a career spanning almost five decades.
This allows prediction of the type of surfactant aggregate micelle, vesicle, bilayer membrane and so on that molecules can form. In , the first edition of his book Intermolecular and Surface Forces was published. With its succinct and accessible style, this text now in its third edition has become a standard reference for students and researchers in many areas of materials science and engineering. He studied physics at the University of Cambridge, first as an undergraduate and then for his PhD with Professor David Tabor whose gentle, inclusive and egalitarian style of supervision he inherited.
A finely developed form of optical interferometry was adapted to measure the separation between two mica surfaces with an accuracy of 0.
Israelachvili made further refinements of the experimental methods, leading to a landmark paper in on the measurement of van der Waals forces in air and vacuum. After a period at the Karolinska Institute in Stockholm, where he embarked on research in membrane biophysics, he was brought back to surface force measurements by Professor Barry Ninham of the Australian National University in Canberra. Ninham, a mathematical physicist, wanted to conduct experimental work to measure the forces that he and his colleagues studied theoretically.
Advised that Israelachvili was the best person for the job, he duly recruited him in Within two years, Israelachvili had built an SFA that could be filled with liquids, greatly extending the suite of forces that could be measured.
His first experiments confirmed the foundations of the classical DLVO theory of colloid stability, and later ones explored its limitations when other forces come into play. Over the next decade, he and his colleagues produced a series of landmark papers showing how surface chemistry and the properties of a liquid or vapour medium determine inter-surface and particle interactions.
In , he moved to the University of California at Santa Barbara. His group was at the forefront of research on the interactions of biological and biomimetic model surfaces across aqueous solutions, underwater adhesives derived from or inspired by mussel foot proteins, and the adhesion mechanism of gecko toes to different types of surfaces. Another area of research, sustained throughout his career, was the elusive origin of hydrophobic forces. He was also one of the pioneers of the field now called nanotribology.
His work on friction and lubrication informed modelling studies by others and led to insights on the stick—slip phenomenon and the relationships between adhesion and friction. Jacob as everyone knew him was an outstanding adviser to his research group and to many others who sought out his company and insights.
He took the time to provide the individualized advice and support each person needed, an approach that was viewed with some envy by members of other research groups and occasional scepticism by their advisers. All data were examined with kind interest, possible sources of mistakes were patiently discussed, new and improved experiments were suggested, and any frustration he may have felt was concealed well. Having designed the instruments himself, he was also the expert on their use.
Always interested in the history and development of scientific thought, Jacob had anecdotes about scientists from every era. His scintillating wit made him an entertaining speaker, and a wonderful companion at any social gathering. Many people around the world have happy memories of their interactions with him.
He will be deeply missed.

Description Intermolecular and Surface Forces describes the role of various intermolecular and interparticle forces in determining the properties of simple systems such as gases, liquids and solids, with a special focus on more complex colloidal, polymeric and biological systems. The book provides a thorough foundation in theories and concepts of intermolecular forces, allowing researchers and students to recognize which forces are important in any particular system, as well as how to control these forces. This third edition is expanded into three sections and contains five new chapters over the previous edition.
