No single person "named" blood. The term "blood" has ancient origins and its naming predates recorded history. However, we can explore the history of our understanding of blood and the terminology surrounding it.
The Ancient Roots of "Blood"
The concept of blood and its significance have existed in human cultures for millennia. Many languages have words for blood derived from ancient roots, reflecting its importance in various contexts—from sustenance to cultural and religious beliefs. The word "blood" itself evolved over centuries through language development.
Scientific Understanding and Terminology
While the word "blood" itself has ancient origins, the scientific study of blood and its components is more recent. The understanding of blood types, for instance, is a relatively modern development.

Karl Landsteiner's Contribution: In the early 20th century, Karl Landsteiner made a groundbreaking discovery by identifying the ABO blood groups (A, B, and O). His work wasn't about naming blood itself but about classifying its types, which was crucial for blood transfusions and preventing adverse reactions. [See reference: In 1900 Landsteiner found out that the blood of two people under contact agglutinates, and in 1901 he found that this effect was due to contact of blood with blood serum. As a result, he succeeded in identifying the three blood groups A, B and O, which he labelled C, of human blood.]

Greek Origins of Medical Terminology: Many medical terms related to blood stem from the ancient Greek word αἷμα (haima), meaning "blood." This demonstrates the longstanding connection between the substance and its study. [See reference: Medical terms related to blood often begin with hemo-, hemato-, haemo- or haemato- from the Greek word αἷμα (haima) for "blood".]
In summary, attributing the "naming" of blood to a specific person is impossible. The term evolved organically through language. Landsteiner's work significantly advanced our understanding of blood, but he didn't name blood itself.
