Nanny and the Professor is an American fantasy situation comedy
1970 - 1971

Premise

Playing upon the popular successes of Mary Poppins and other magical
nannies of literature, this TV series posited another ostensibly magical
British nanny taking care of a family in need of guidance. Unlike the candid
"magicality" of its forebears, this Nanny's paranormal nature was less
overt and only implied. The Nanny's young wards, as well as the audience,
were left intentionally uncertain of the nature of Nanny's "powers", if any.

The series starred Juliet Mills as Nanny Phoebe Figalilly, Richard Long as
Professor Harold Everett, and in season 3 Elsa Lanchester in the recurring
role of Aunt Henrietta. Figalilly was housekeeper for Professor Everett as
well as nanny to his three children: Hal, the intellectual tinkerer, played by
David Doremus; Butch, the middle child, played by Trent Lehman; and
Prudence, the youngest, played by Kim Richards.
Nanny was apparently psychic, and had regular flashes of what was often
more than intuition (accented by a musical tinkling sound effect); she
frequently knew who was at the door before the doorbell even rang.
There was the vague suggestion that she may have been at least several
hundred years old and more than human, which the children thought they
discovered in an episode after they saw a photo of Phoebe that looked like
it was taken a century earlier. On outings, Nanny wore a navy blue Inverness
cape and cap that resembled a deerstalker; the program's opening titles
showed animations of both. Midway through the first season Nanny and the
kids restored a broken down 1930 Model A Ford, which Nanny nicknamed
"Arabella"; for some reason the car's radio can only pick up radio broadcasts
from 1930.
