every day I come in here, frightened by that." And that was such a wonderful thing to have heard about science. ..."I realize this is a hypothesis. We’re doing experiments that support the hypothesis, and it gives us confidence that the hypothesis is an accurate description of the world, some part of the world. But it's a hypothesis and we must never forget that. There was timidity, tentativeness in
Francis's attitude towards scientific results, in that despite the success of his creative hypotheses he remained open to any results that will disprove it. And so it was really a lovely illustration of what science could be." (2019 Oral History). Another day Francis, in a discussion, said we could do Sidney's experiment which meant trying to experimentally identify chain terminators in the DNA which I volunteered to do and with guidance from Leslie Barnett managed to accomplish. But instead of continuing in Molecular Biology I was more interested in charting new directions for biological NMR and returned to Bell Labs to follow NMR and other spectroscopic studies of biological materials and organisms. With Terry Eisinger and Bill Blumberg I built up a group of young scientists which eventually became the Biophysical Research Department. Over several decades, we pioneered in the use of nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), other forms of spectroscopy and EXAFS to study biochemical processes. The research soon focused on non-invasive nuclear magnetic resonance studies in vivo of humans and animals

enzymes not, as usually considered, to control pathway flux but to maintain homeostasis of biochemical intermediates. This established the ability to measure glycogen in vivo which, with the cooperation of two clinical colleagues, Gerry
Shulman and Ralph De Fronzo, and actually performed by Doug Rothman who had become the scientific strength of our effort, was used to measure glucose pathways in Type 2 Diabetics as compared to controls. This showed that the flux of glycogen synthesis, which stored glucose as muscle glycogen, was controlled, not by Glycogen Synthase, as had been assumed, but by glucose transporters that were inadequately mobilized in Type 2 patients, and has subsequently been developed by Doug Rothman and Gerry Shulman as the mechanism of this prevalent pathology. "13CNMR studies of the human brain, once again led by Doug Rothman, measured the flux of the glutamate/glutamine cycle thereby quantitatively unifying electrical, neurotransmitter and electrical brain measurements which now form the basis of brain function. To the extent that these in vivo measurements of brain, yeast and muscle have succeeded in showing the powers of NMR and other spectroscopic measurements of energy the goal that I set in 1962 of unifying the strengths of Bell Labs and the LMB of Cambridge is being reached. In addition to the collaborators mentioned or unfortunately neglected in this account thanks are due to the Guggenheim Foundation whose far-sighted understanding of science made it possible." He was a

joined the physics research department at Bell
Telephone Laboratories in Murray Hill, N.J., where he began research on the use of NMR in condensed matter physics particularly studying magnetic materials like paramagnetic fluorides where he defined the covalent bonds and the exchange reactions responsible for their anti-ferromagnetism in these primarily ionic compounds. Eventually he became interested in Russian claims that DNA was a magnetic material which he showed were mistaken. In 1961 he received a Guggenheim Fellowship to study abroad as a visiting Professor of Physics at the Ecole Normale in Paris which, because his interests had shifted to biological materials, he transferred, with the blessing of the Guggenheim, to the Laboratory for Molecular Biology in Cambridge. "There was all sorts of speculation about DNA," he said while still at Bell Labs "so I went back to Alex Rich, who was by then an established biologist. I said, 'I'd like to go into biology, where should I go on my sabbatical?' The answer was 'Go work with Francis Crick if you can.'" In 1961–1962, he worked with Crick and Sidney Brenner in Cambridge, "in the old courtyard of the Cavendish Lab", helping to put "the finishing touches to Crick’s hypothesis as to how the DNA code was read for synthesizing proteins".

function of biochemistry, at that time generally ignored in the search for genetic knowledge, but which I felt could be re invigorated by the physical methods developed at Bell Labs. In this way I was combining the development of a physical technique with an extension of its applicability to biological problems by which I followed the practices of the two world-famous laboratories where I had worked. With that intention I returned to Bell Labs and started a biophysics department which attracted a wonderful group of scientists, where we studied biomolecules and developed in vivo methods of following by NMR the biochemical pathways of stable isotopes. Members of this
Department subsequently went on to exciting developments, on their own, which earned one Nobel Prize, Kurt Wuthrich, the invention of fMRI by Seiji Ogawa, and of neural nets by John Hopfield.” (2019 Oral History). They extended NMR in vivo and filled many important positions in academia, industry and government.ral History)
