[edit] Paperclip invention date

It says on the 1900 page he invented it in 1900, but here it says 1899 and 1901. --DOsinga 18:57, 21 August 2005 (UTC)

Johan Vaaler applied for a German patent on Nov. 12, 1899. It was granted June 6, 1901 (No. 121.067). His US patent (No. 675.761) dates from June 4, 1901. His application was filed Jan. 9, 1901. (See Foss, Halvard: "Den frittstående oppfinner", in the report of the first 50 years of the Norwegian Patent Office, (undated) Oslo, pp.188-195.) Roede 08:55, 16 January 2007 (UTC)

[edit] Death date

His LoPbN entry said

*Vaaler, Johan, (1866-??) inventor of the paperclip

and an earlier edit of his bio said

Johan (or Johann) Vaaler (March 15, 1866[1] - ????)

(But note that the link is to an article that doesn't mention either a death date or specific doubt about it.)

An anon edit supplied the current death date.

I put 1910 into LoPbN, assuming it's just behind the curve.

Johan (not Johann) Vaaler was born in Aurskog, Norway on March 15, 1866. He died in Kristiania on March 14, 1910. (Norsk Biografisk Leksikon, Vol. 9, 0slo 2005, p. 411). I am the anonymous person who contributed the year of his death, but at that time I had not been able to find the date. Roede 08:55, 16 January 2007 (UTC)
