Karoline "Lina" Radke-Batschauer (18 October 1903 – 14 February 1983) was a German track and field athlete.

This vision was shared by many, including the originator of the modern Olympic movement, Pierre de Coubertin.

The couple moved to Georg's hometown of Breslau (now Wrocław in Poland), where in 1927 she set her first 800 m world record.

The highlight of Radke's career were those 1928 Summer Olympics, as she won the inaugural title in the 800 m, earning the first German gold medal in athletics.

Following false media reports[1] of competitors collapsing after the race, however, the IOC banished the women's 800 m from the Games; it would not be included again until 1960.
