James-
Indeed, but when he posted the link, it was to what is now located at [[Baltzar von Platen (1898-1984)]]. Such is the Wikipedia, after all. Perhaps one could look at the page's history, but...
Aha.
I don't know about that von Platen's historical significance, and the article certainly doesn't give me a good idea of it. The way it stands right now, I would prefer the relevant information to be moved to an article about the [[gas absorption refrigerator]], especially since much of it does not refer to the person but to the historical context:
"In 1923 production by AB Arctic began. In 1925 AB Arctic was purchased by Electrolux which began selling them worldwide. Servel purchased rights to manufacture the refrigerator in 1925 and was the only U.S. manufacturer for many years."
If all von Platen is famous for is his participation in the development of refrigerators, then no, I do not think he necessarily needs his own article. That's what redirects are for.
