History Of Tofu
Tofu is one of the world's oldest plant-based foods, with a history spanning more than 2,000 years. It originated in ancient China and gradually spread throughout East and Southeast Asia before becoming a staple ingredient worldwide.
The earliest records suggest that tofu was invented during the Chinese Han dynasty (206 BCE–220 CE). It is traditionally attributed to Liu An, a nobleman and scholar who lived around 179–122 BCE. According to legend, Liu An accidentally discovered tofu while experimenting with soybeans and mineral salts.

Porter W. Anderson Jr. and David Hamilton Smith were two of the four scientists principally responsible for developing the Haemophilus influenzae type b (Hib) vaccine. Their work transformed Hib from a leading cause of childhood meningitis into a largely vaccine-preventable disease
Their research began in the late 1960s at Boston Children's Hospital, where they investigated why Hib caused severe infections in infants and young children. Anderson, a microbiologist, and Smith, a pediatric infectious disease specialist, identified the bacterium's capsular polysaccharide—polyribosylribitol phosphate (PRP)—as the critical antigen capable of inducing protective immunity.
