"Albert Einstein presented the theories of special relativity and general relativity in publications that either contained no formal references to previous literature, or referred only to a small number of his predecessors"

Elsa Einstein (18 January 1876 – 20 December 1936)[1] was the second wife and cousin of Albert Einstein. Their mothers were sisters, thus making them maternal first cousins. The couple were also paternal second cousins (i.e., their fathers were first cousins)
