Wenkoff was born on August 17, 1921 in Veliko Turnovo (actually Trnovo).
He studied at a commercial high school, while helping at his
father's textile business during his free time. When Wenkoff finished, he went to Vienna where he studied world trade at the University.
It is not known when Wenkoff discovered his love for opera, However, one evening of 1942, he is in front of the Staatsoper
where Rigoletto is
being performed that evening. He wanted to attend but how? He asked the concierge to tell the Bulgarian singer Pantschev
that a young Bulgarian wants
to see him.
Pantschev is already in costume, when Wenkoff ask him for a free ticket. Pantschev has already given away his free tickets,
Wenkoff to visit him the next day.
The next day, Wenkoff tells Pantschev that he wants to be an opera singer and that he is a tenor.
Pantschev sits down at the piano and asks Wenkoff to sing. Pantschev is very surprised he hears a natural voice
with wonderful high notes.
Pantschev introduce him to his teacher who encoureage him to study. He becomes student of Marga Wissmann who
is impressed by his natural singing. From that time on, he spends his free evenings at the Volksoper or Staatsoper,
and study hard.
After preparing Nemorino and Rodolfo arias, Marga Wissmann introduced him to Karl Böhm. Böhm is enthusiastic
and begins to prepare with Wenkoff the role of Rodolfo. Without any contract yet, when the tenor singing Rodolfo cancels,
replaces him on January 21, 1944 at the Staatsoper and has a great success. The newspaper Wiener Kurier writes:
We have not heard in years such fresh, noble and delightful voice.
