MP Sophie Williams de Bruyn was congratulated on her achievement, the office of the ANC chief whip said.
Spokesperson Moloto Mothapo described Williams de Bruyn as "a veteran leader of our movement and a champion of the women's struggles".
"It is an honour and a privilege to still have women and veteran activists of such outstanding quality serving in this institution," Mothapo said.
"It is truly a momentous and fitting tribute for her to be given such recognition by a city whose streets she could not freely walk as a young activist, without being harassed for merely being born a woman and black."
