What composers dad made him get out of bed in the night to practice until morning?

The composer you’re referring to is Sergei Rachmaninoff. His father, a military officer, was strict and insisted that Rachmaninoff practice the piano intensely, even making him get out of bed at night to do so. This demanding upbringing contributed to Rachmaninoff's exceptional talent and later success as a composer and pianist.
