German satirical poet of unknown date. The only poem of his that has been preserved is a satire of seven strophes, ending with a refrain in which he very wittily criticizes the inhabitants of the Rhine province. Although his vocabulary is not always pure, the versification is perfect and betrays great ability. The name "Gumplin" is given in acrostic. Abraham Geiger published the poem, together with a German translation, in his "Melo Chofnajim."
