As quoted in "Atom Energy Hope is Spiked By Einstein / Efforts at Loosing Vast Force is Called Fruitless," Pittsburgh Post-Gazette (29 December 1934); it was only after the breakthroughs by Enrico Fermi and others in producing nuclear chain reactions that the use of nuclear power became plausible.

Letter to Eileen Danniheisser (1953), quoted in Albert Einstein: Creator and Rebel by Banesh Hoffman (1973), p. 261 http://books.google.com/books?id=sdDaAAAAMAAJ&q=%22think+with+fear%22#search_anchor. The exact date, or the name of his correspondent, is not given in the snippet of the book available online, but the quote appears after the letter to the Queen of Belgium from 12 January 1953, and is prefaced by "Nine months later, in words that recall the beliefs of an early atomic speculator, the Roman poet Lucretius, Einstein had written to an inquirer", followed by the quote. The name "Eileen Danniheisser" is given in Time: Volume 144, where it is mentioned in the snippets here http://books.google.com/books?id=JDAnAQAAIAAJ&q=%22obsessive+thoughts%22#search_anchor and here http://books.google.com/books?id=JDAnAQAAIAAJ&q=%22think+with+fear%22#search_anchor that she had written Einstein "about her obsessive thoughts of death as a child".

The equivalence of mass and energy was originally expressed by the equation m = L/c², which easily translates into the far more well known E = mc² in Does the Inertia of a Body Depend Upon Its Energy Content? http://www.fourmilab.ch/etexts/einstein/E_mc2/www/ published in the Annalen der Physik (27 September 1905) : "If a body gives off the energy L in the form of radiation, its mass diminishes by L/c²."
In a later statement explaining the ideas expressed by this equation, Einstein summarized: "It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing — a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned before. This was demonstrated by Cockcroft and Walton in 1932, experimentally."
