Modern name for HD 33793 = GJ 191, a high proper motion M1 subdwarf at d=4pc (V=8.8) in Pictor. The star was unusual – very blue but M1 type, high pm and very high radial velocity (242 km/s). Two recent exoplanet candidates reported (Anglada-Escude+2014) but both have been rebutted (Bortles+2021).
Etymology and History
This was 2nd-highest proper motion star in 1927 according to Luyten and still is! (8.7”/yr). It was pointed out as highest proper motion (at time) by Kapteyn (1897) “Stern mit grösster bislang bekannter Eigenbewegung” (“Star with largest self-motion known to date”)
The name appears to be from Luyten (1927) “Note on the Magnitude and Spectrum of Kapteyn's Star”.

IAU Star Name
WGSN discussed the name in 2022 but decided (for the time being) not to name stars after people.
