  Felix Bloch Biography | Encyclopedia of World Biography
Felix Bloch (1905-1983) is best known for his development of nuclear magnetic resonance techniques, which allowed highly precise measurements of the magnetism of atomic nuclei and became a powerful tool in both physics and chemistry to analyze large molecules.
Bloch was born in Zurich, Switzerland, on October 23, 1905, the son of Agnes Mayer Bloch and Gustav Bloch, a wholesale grain dealer.
The Bloch T 3/2 law describes how magnetization in ferromagnetic material is dependent upon temperature, Bloch walls are the transition region between parts of a ferromagnetic crystal that are magnetized with different orientations, and the Bloch theorem eliminates some of the possible explanations for superconductivity.

 Felix Bloch (alleged spy) - Wikipedia, the free encyclopedia
Felix Bloch (born 1933) a former senior American diplomat living in Washington, D.C., and the second most important in the U.S. embassy in Vienna, has fallen under accusations of espionage activities to the Soviet Union, thus becoming the most important person to fall under such accusations since World War II.

Shortly afterward, Bloch, the head of the State Department's European section, was tipped off to the investigation by FBI counterintelligence specialist Robert Hanssen, the FBI says in an affidavit it filed last week.
According to the affidavit and interviews with intelligence sources, the investigation of Bloch began in late April 1989 after he was detected on a wiretap talking to Reino Gikman, an undercover agent for the Soviet KGB who operated in Western Europe.
The CIA, working with the French, proposed that Bloch be nabbed en route to the Paris meeting or during a second meeting scheduled with Gikman for Brussels later in May. A team was assembled and a plan was developed to grab Bloch off the street and confront him with evidence.

A paper exploring the strong dispersion in one-dimensional periodic structures, illustrating for the first time the propagation of a Bloch wave pulse in a fibre Bragg grating, was published in 1991 [15].
In two further studies this work was extended to the design of hexagonal photonic crystal films both as waveguides [19] and as high Q resonators [20].
This was followed by the design of a quasi-metallic (sometimes known as omni-directional) multilayer structure that exhibited all the features of a photonic band gap material, providing strong suppression of spontaneous emission [24].

For even while Bloch offers us a chronicle of pain, she demonstrates that 'the end of safety' is the beginning of revelation and transformation, as 'Lightning flares at the windows / zinc-white' in a 'wind that can drive / a nail through a tree trunk.'"—Sandra Gilbert
