Rapid Response:

Niels Bohr wasn't the first

In the commentary following this remarkable piece of prognostic research a famous Danish joke is quoted: "It is difficult to prophesy -- especially when the future is involved." The saying, which has been popular in Denmark since the 1950s, was attributed to Niels Bohr (1885- 1962). He may well have used it. Most Danes, however, ascribe it to his contemporary Robert Storm-Petersen, known as 'Storm P.' (comedian, cartoonist, painter, writer, 1882-1949).

In actual fact it is not a joke at tall but a slip of the tongue, committed by an anonymous member of the Danish parliament in the late 1930s and recollected by a fellow politician (K. K. Steincke, 1880-1963, known as the father of modern welfare legislation)in his 1948 memoirs.

At least this is what I have been able dig up by consulting various domestic sources of information.
