With all the demands of living in the present and concerns about the future, why do people care about what happened in the past? Everything we do, every item we use, and all the things we experience in our daily lives are shaped by our past. The foundation for our traditions, technologies, and everything in between was laid by those who came before us.

Our understanding and knowledge of topics increases over time due to historical perspectives. Photographs from the past aren’t just about people, they show us how humans lived decades ago and how their actions have impacted our lives.

Her image became a symbol of courage and dignity and still inspires people globally to stand up against any discrimination.

Images taken after the San Francisco earthquake and subsequent fire in 1906 captured not just the destruction but also the resilience of the people affected.
