Daresbury Laboratory) is an English theoretical physicist known for his research into refractive indices and creation of the first practical "Invisibility Cloak". He is a professor of theoretical solid state physics at Imperial College London where he was head of the department of physics (1998–2001) and principal of the faculty of physical sciences (2001–2002). He is an honorary fellow of Downing College, Cambridge, (where he was an undergraduate) and an IEEE fellow. He received the Kavli Prize in Nanoscience "for transformative contributions to the field of nano optics that have broken long held beliefs about the limitations of the resolution limits of optical microscopy and imaging. ", together with Stefan Hell, and Thomas Ebbesen, in 2014.

Pendry was educated at Downing College, Cambridge, graduating with a Master of Arts degree in Natural Sciences and a PhD in 1969.

John Pendry was born in Manchester, where his father was an oil representative, and took a degree in Natural Sciences at the University of Cambridge after which he was appointed as a research fellow at Downing College, Cambridge, between 1969 and 1975. He spent time at Bell Labs in 1972–3 and was head of the theory group at the SERC Daresbury Laboratory from 1975 to 1981, when he was appointed to the chair in theoretical physics at Imperial College, London, where he stayed for the rest of his career. Preferring administration to teaching, he was Dean of the Royal College of Science from 1993 to 1996, head of the Physics Department from 1998 to 2001 and Principal of the Faculty of Physical Sciences 2001–2. He has authored over 300 research papers and encouraged many experimental initiatives. He was elected a Fellow of the Royal Society in 1984 and in 2004 he was knighted in the Birthday Honours. In 2008, an issue of Journal of Physics: Condensed Matter was dedicated to him in honour of his 65th birthday. He is married to Pat, a mathematician he met at Cambridge who became a tax inspector. They have no children. His hobbies include playing the piano. and several books. Pendry's research career started with his PhD, which was concerned with Low energy electron diffraction (LEED), the second stage, and has further expanded to diffusion systems the third stage. The control equations for these three stages are completely different, namely Maxwell equations (a type of wave equation for transverse waves), other wave equations (used to describe both longitudinal and transverse waves), and diffusion equations (used to describe diffusion processes). Therefore, from the perspective of control equations, researchers today can divide the field of metamaterials into three main branches: Electromagnetic/Optical wave metamaterials, other wave metamaterials, and diffusion metamaterials. Diffusion metamaterials are crafted to master various diffusion dynamics, where diffusion length serves as the pivotal measure. This parameter fluctuates over time, yet it does not respond to alterations in frequency. Conversely, wave metamaterials, tailored to modify diverse wave travel patterns, hinge on the wavelength of the incoming waves as their vital measure. Unlike diffusion length, wavelength stays steady over time but varies with frequency changes. At their core, the primary measures of diffusion and wave metamaterials diverge significantly, highlighting a unique complementary connection between the two; more details can be found in Section I. B "Evolution of metamaterial physics" of Ref. In 2009 he and Stefan Maier received a large grant from the Leverhulme Trust to develop the ideas of perfect lens and invisibility cloak in the optical range of light.
