Alfred Nobel
suffered from angina pectoris and was prescribed nitroglycerine. In a letter to a friend he wrote:

  “It sounds like the irony of fate that I have been prescribed nitroglycerine internally. They have named it Trinitrin in order not to upset pharmacists and the public.

Your affectionate friend,

A. Nobel”
