Frederick Griffith's experiments in 1928 demonstrated the phenomenon of transformation in bacteria, leading to the discovery that DNA is the material of heredity. His work with Streptococcus pneumoniae revealed that non-virulent strains could become virulent when exposed to heat-killed virulent strains, laying the groundwork for molecular genetics. Although Griffith himself did not identify DNA as the transforming principle, his findings significantly influenced subsequent research, ultimately contributing to the understanding of genetic material. This pivotal research set the stage for the later identification of DNA as the carrier of genetic information.

Additionally, Douglass collaborated with other activists and intellectuals, such as Wendell Phillips and Julia Griffiths, who helped him refine his ideas and provided editorial support. Their encouragement and guidance were instrumental in shaping his powerful narrative, which became a cornerstone of American literature and abolitionist thought.

Frederick Douglass had a lasting impact primarily in the 19th century as a prominent abolitionist, orator, and advocate for civil rights. His autobiographies, notably "Narrative of the Life of Frederick Douglass, an American Slave," shed light on the horrors of slavery and inspired the abolitionist movement. Douglass's advocacy for equality extended beyond slavery to women's rights and social justice, influencing future generations in their struggles for civil rights. His legacy continues to resonate today as a symbol of the fight for freedom and equality.

Frederick Griffiths observed natural transformation for the first time, while he was searching for the pneumonia vaccine. He discovered that mixing a heat killed pathogenic strain of bacteria with a living nonpathogenic strain converted some cells into the pathogenic form.
