So, this is my agenda, there is not yet an article about my dad, Dr. Alfred G. Redfield, though there are about his dad Alfred C. Redfield and his Great(?) Grandfather William C. Redfield.
In addition to his achievements and respect (his best paper got 1776 citations), there is the potential to some charming links about further family, also some of the theories. The redfield theory is already up on Wikipedia...
The 136 citations are formatted, and thinking about how to create a narrative based on periods of his scientific life. Of course, his papers are in a very foreign language, so it will take some time to translate into a good story.
2 Obituaries mixed together:
Al was one of the giants of nuclear magnetic resonance (NMR), in terms of both his contributions to fundamental science and the practical application of magnetic resonance to real world problems. As a teenager during World War II, he learned circuitry and electronics that he would later apply to building his own NMR spectrometers. However, his genius was not limited to NMR; Redfield relaxation theory has been applied to statistical mechanical and spectroscopic systems throughout the physical sciences. He was elected to the National Academy of Sciences in 1979 and named a Fellow of the American Academy of Arts and Sciences (AAAS) in 1983. Al received the Max Delbrück Prize from the American Physical Society in 2006.
Education and the IBM years
Al was born in Milton, Massachusetts, and was named after his maternal great uncle, Alfred Guillou (1859– 1921). He grew up in Cambridge and then in Woods Hole, Massachusetts, where his father, Alfred C. Redfield, worked at the Oceanographic Institute. He graduated from Harvard College in 1950 with a bachelor’s degree, a master’s in 1952, and then obtained his Ph.D. in 1953 from the University of Illinois at Urbana-Champaign. His Ph.D. thesis concerned the Hall Effect in diamonds and alkali metal halogens. Al’s thesis acknowledges “Professor C. P. Slichter and his associates for their friendliness and cooperation while I was occupying their magnet and laboratory.” Al and Charlie Slichter remained good friends throughout their lives. After returning to Harvard for a postdoc with Nicolaas Bloembergen, Al published a 1955 Physical Review paper titled “Nuclear Magnetic Resonance Saturation and Rotary Saturation in Solids,” in which he established the concept of spin temperature in the rotating frame, including spin-locking, T1ρ relaxation, and dipolar order that were essential to many subsequent developments (1). In his Principles of Magnetic Resonance, Slichter called this paper “one of the most important papers ever written on magnetic resonance.” A more general treatment was published in Science in 1969 (2).

After returning to Harvard for a postdoc, he published a 1955 Physical Review paper "Nuclear Magnetic Resonance Saturation and Rotary Saturation in Solids" in which he established the concept of spin temperature in the rotating frame, including spin-locking, T1 relaxation, and dipolar order that were essential to many subsequent developments. In his Principles of Magnetic Resonance, Slichter called this paper "one of the most important papers ever written on magnetic resonance". A more general treatment, "Nuclear Spin Thermodynamics in the Rotating Frame", was published in Science in 1969.
Al then took a position at IBM Watson Laboratories at Columbia University, where he remained until 1970. There he pursued applications of NMR in solids, as well as fundamental aspects of magnetic resonance. His work included measurements of spin-lattice relaxation in metals at very low temperatures (Anderson and Redfield, Phys. Rev. 1959), analysis of spin relaxation in solids driven by translational diffusion (Eisenstadt and Redfield, Phys. Rev. 1963), investigations of the properties of impurities in copper using field cycling (Redfield, Phys. Rev. 1963), the first demonstration of NMR for characterizing the vortex lattice in a type II superconductor (Redfield, Phys. Rev. 1967), and experiments and theory to show that spin diffusion in a magnetic field gradient generates dipolar order (Genack and Redfield, Phys. Rev. Lett. 1973). He also developed an indirect detection method for rare spins, observing natural abundance 43Ca in CaF2 using 19F (Bleich and Redfield, J. Chem. Phys. 1971), the intellectual ancestor of contemporary indirect detection methods.
In 1957, Al published his theory of spin relaxation, the eponymous Redfield Theory, in the IBM Journal of Research and Development. Years later, John Waugh, the editor of the nascent Advances in Magnetic Resonance, convinced Al to publish the theory "for real". His article became the centerpiece of the premier issue of that monograph series (Adv. Magn. Reson. 1, 1 (1965)). Redfield Theory as applied to statistical mechanical and spectroscopic systems has found applications throughout the physical sciences. Even so, Al would say of his theory when asked, "Well, it was just a better way of writing down what everybody already knew". In 1970, Al received the IBM Outstanding Contribution Award for his development of a high-resolution pulsed NMR spectrometer, which included one of the earliest implementations of quadrature detection in time-domain NMR (Redfield and Gupta, Adv. Magn. Reson. 1971). He also received a faculty appointment at Columbia. In 1969, he began using NMR to investigate biological materials during a sabbatical with Dan Koshland at U.C. Berkeley. In 1972, he joined the faculty at Brandeis University, with a joint appointment in physics and biochemistry, where he remained for the rest of his career.
He became a National Academy of Sciences member in 1979 and an American Academy of Arts and Sciences Fellow in 1983. Al received the Max Delbruck Prize from the American Physical Society in 2006.
Al's many pioneering contributions to biological NMR include early studies of electron transfer in cytochrome c using saturation transfer (Gupta and Redfield, Science 1970), solvent suppression via composite pulse excitation (Redfield, Kunz, and Ralph, J. Magn. Reson. 1975), measurements of hydrogen exchange rates in tRNA and proteins (e.g., Johnston, Figueroa, and Redfield, PNAS 1979; Stoesz, Redfield, and Malinowski, FEBS Lett 1978), and an early 1H-detected 2D 15N-1H correlation experiment that he referred to as the “forbidden echo” (Redfield, Chem. Phys. Lett. 1983).
Al would have been as comfortable in an engineering department as he was in physics. His home-built NMR spectrometer at Brandeis was the first instrument designed to specifically target biological systems. He optimized selective pulses for water suppression years before pulse trains such as WATERGATE and flip-backs came into common usage. Al’s first superconducting magnet, a 6.4 T magnet acquired in the early 1980s, was brought to field at Bruker in Billerica, MA and shipped cold and charged to Brandeis on a flatbed, a 20-mile trip. FIDs on his earlier instrument were digitized as they were acquired and stored on a 2048-bit ring memory before being passed to an IBM PC for Fourier transformation and analysis. All processing software was written by Al, as were the pulse sequences.
(obit #1)The IBM Years
Al then took a position at IBM Watson Laboratories at Columbia University, where he remained until 1970, pursuing applications of NMR in solids, as well as examining some fundamental aspects of magnetic resonance. His work at IBM included measurements of spin-lattice relaxation in metals at very low temperatures (3), analysis of spin relaxation in solids driven by translational diffusion (4), investigations of the properties of impurities in copper using field cycling (5, 6), the first demonstration of NMR for characterizing the vortex lattice in a type II superconductor (6), and experiments and theory to show that spin diffusion in a magnetic field gradient generates dipolar order (7). He also developed an indirect detection method for rare spins, observing natural abundance 43Ca in CaF2 using 19F (8), the intellectual ancestor of contemporary indirect NMR detection methods.
In 1957, Al published his theory of spin relaxation, the eponymous Redfield Theory, in the IBM Journal of Research and Development[ref group 1]. Years later, John Waugh, the editor of the nascent Advances in Magnetic Resonance, convinced Al to publish the theory “for real.” His article became the centerpiece of the premier issue of that monograph series (9). Even so, Al would say of his theory when asked, “Well, it was just a better way of writing down what everybody already knew.” In 1970, Al received the IBM Outstanding Contribution Award for his development of a high-resolution pulsed NMR spectrometer, which included one of the earliest implementations of quadrature detection in time-domain NMR (10). He also received a faculty appointment at Columbia. In 1969, he began using NMR to investigate biological materials during a sabbatical with Dan Koshland at the University of California, Berkeley.
The Brandeis Years
In 1972, Al joined the faculty at Brandeis University in Waltham, Massachusetts, with a joint appointment in physics and biochemistry, where he remained for the rest of his career. Brandeis was less than a quarter-century old at the time, having been established in 1948. But a forward-looking administration was in the process of building a world-class biochemistry department (with people such as Robert Abeles and William Jencks among the faculty), and many of Al’s pioneering contributions to biological NMR were done at Brandeis, including early studies of electron transfer in cytochrome c using saturation transfer (11), solvent suppression via composite pulse excitation (12), measurements of hydrogen exchange rates in tRNA and proteins (13, 14), and an early 1 H-detected 2D 15N-1 H multiple-quantum correlation experiment that he referred to as the “forbidden echo” (15, 16).
