Josef Strauss (August 20, 1827 – July 22, 1870) was an Austrian composer.
He was born in Vienna, the son of Johann Strauss I and Maria Anna Streim, and brother of Johann Strauss II and Eduard Strauss. His father wanted him to choose a career in the Austrian Habsburg military. He studied music with Franz Dolleschal and learned to play the violin with Franz Anton Ries.
He received training as an engineer, and worked for the city of Vienna as an engineer and designer. He designed a horse-drawn revolving brush street-sweeping vehicle and published two textbooks on mathematical subjects. Strauss had talents as an artist, painter, poet, dramatist, singer, composer and inventor.
