Frederick Griffith's experiments demonstrated that DNA serves as the genetic/hereditary material. He conducted experiments with Streptococcus pneumoniae and found that when heat-killed virulent bacteria were injected into mice along with non-virulent live bacteria, the mice still died. This indicated that some factor from the dead virulent bacteria had transformed the non-virulent bacteria into virulent ones. This factor was later identified as DNA.
