Carl Otto Reventlow

There he became a member of the student fraternity Corps Saxonia [1] and made contact to political circles and started first publications.

After publishing a textbook on his mnemonic system in 1843,[2] he travelled widely in Germany to popularize it.

[7][8] Otto subsequently involved himself in the revolutionary events of 1848, and came under police investigation in 1849.

[9] Apparently he was the Carl Otto-Reventlow who took over a Cincinnati radical, anti-monarchist periodical for German-speaking exiles, the Hochwächter, in 1857.

[10] He appears to have had some contact with Karl Marx, who referred to him in extremely derogatory terms in at least one of his letters.
