In the realm of science, Alva Edison (1847-1924) was the younger brother of the renowned inventor Thomas Edison. Although not as famous as his brother, he played a significant role in the development of several of Thomas Edison's inventions.

The name Alva also found its way into the literary world. Alva Tressler (1868-1937) was an American author and educator, known for her children's books and textbooks on hygiene and health education.

Lastly, Alva R. Fitch (1907-1989) was an American military officer who served in World War II and the Korean War. He received the Distinguished Service Cross, the second-highest military decoration in the United States, for his acts of valor during combat operations.
