Biography

Frisch was born in São Paulo in 1930, the son of Danish immigrants Svend Frisch and Ellen Margareth Dalgas Frisch, who came to reside in Brazil in 1927. His maternal grandfather was Enrico Dalgas, a famous Danish forester. From an early age, he observed local birds and their behavior, an interest encouraged by his father. Svend Frisch was an artist who among other things drew Brazilian birds, eventually including some illustrations for books he coauthored with Johan.

In 1950, Frisch enrolled in the

Universidade Presbiteriana Mackenzie in São Paulo, graduating with a degree in industrial engineering in 1955. His first job was at a power line factory. In 1958, he travelled to his employer's headquarters in Scotland
. He made use of this opportunity to meet European ornithologists, and was introduced to their collections of recordings of bird songs.

On returning to Brazil, Frisch started recording birds, initially using a cardboard funnel. He refined this design as he made recordings, and eventually made a parabolic dish for the same purpose. On a trip to the Pantanal, he made several recordings of the local birds.

In 1962, Johan released some of his recordings as an album on

Christmas songs such as Silent Night and Jingle Bells
interspersed with sounds of birds.

In 1964, he published the book Aves Brasileiras, coauthored with his father Svend.

Also in 1964, his son Christian was born. Frisch had a successful career as an engineer, and in 1976 designed the wastewater treatment station at

5 October. In 1992, he received the title of Honorary Citizen of Texas for having rescued and repatriated one peregrine falcon
that had been banded in Texas.

In 1994, he published a book on hummingbirds coauthored with his son Christian, Jardim dos Beija-flores. In 2001, he published Os 12 Cantos do Brasil, and in 2002 his fourth book Cantos Harmoniosos da América. In 2005, he published the third edition of Aves Brasileiras, now including a section on plants that attract birds and accordingly entitled Aves Brasileiras e Plantas que as Atraem. Many drawings in the book were those were made by Svend for earlier editions, and some of the rest were by Christian.
