Biographies are detailed accounts of a person's life, often highlighting their achievements, struggles, and contributions to society. They provide readers with insights into the experiences that shaped the individual, making them a valuable resource for understanding historical and contemporary figures like Albert Einstein or Marie Curie. These narratives can be written in various styles, from academic to narrative, and can cover a wide range of subjects, including politicians, artists, and scientists. Biographies not only celebrate individual accomplishments but also reflect the cultural and social contexts in which these figures lived.
