Emil von Qvanten (22 August 1827 – 5 December 1903) was a Finnish-Swedish poet, librarian, publisher and politician.
Qvanten went in to exile in Stockholm, Sweden, whnce he produced anonymous political propaganda which was smuggled into Finland. In 1855 Oskar Tammelander, working for the Russian secret police went to Stockholm and met Qvanten, but aroused Qvantend's suspicions. So Qvanten supplied the infiltrator with a letter full of literary parodies to excite the suspicions of his contacts in Finland. This succeeded and Tammelander was unmasked as a spy.[1]
