Cam Lyman (September 4, 1932 – sometime between 1987–1995), born Camilla Lowell Lyman in Westwood, Massachusetts, was a multimillionaire breeder of champion Clumber Spaniels who notably died under mysterious circumstances.
 He was assigned female at birth.
 The Independent reported, however, that, as an adult, Lyman was "known to acquaintances as a man" and cultivated "a male identity."
 Lyman's family members, however, have contended that there's no evidence that Lyman ever received sexual reassignment surgery and that therefore he should still be considered a woman.
 Lyman disappeared in 1987 and was declared dead in 1995.

In physics, a Fano resonance is a type of resonant scattering phenomenon that gives rise to an asymmetric line-shape.
 Interference between a background and a resonant scattering process produces the asymmetric line-shape.
 It is named after Italian-American physicist Ugo Fano, who gave a theoretical explanation for the scattering line-shape of inelastic scattering of electrons from helium; however, Ettore Majorana was the first to discover this phenomenon.
 Because it is a general wave phenomenon, examples can be found across many areas of physics and engineering.
