The Hoover Sentinels

The Hoover Sentinels was a radio concert series which was broadcast on NBC from 1927 to 1935. Sponsored by Hoover Vacuums, it was sometimes heard as Madame Schumann-Heink, Hoover Sentinels Serenade, Sentinels Serenade or Hoover Sentinels.

The 30-minute program initially aired on Sunday evenings at 10pm and later on Sunday afternoons at 5pm. In 1934-35 it was in the top ten of the highest-rated radio programs.

The program's vocalist was contralto Ernestine Schumann-Heink, who also was heard on Enna Jettick Melodies. In 1934, she also did a 15-minute Sunday evening series for Gerber's baby food.

When The Hoover Sentinels came to an end in 1935, the 5pm timeslot was taken over by The General Motors Hour.
