**Ernst Witebsky** (September 3, 1901 – December 7, 1969) was a prominent German-American immunologist known for his groundbreaking work in the field of immunology, particularly in the development of procedures for the isolation and partial characterization of A and B blood antigens. His innovative approach also led to the practice of neutralizing certain antibodies in the blood of universal blood donors, significantly advancing transfusion medicine.

Witebsky’s contributions to the understanding of autoimmune diseases were further solidified in 1957 when he co-authored a pivotal paper that first formulated “Witebsky’s postulates.” These criteria have since been fundamental in determining whether a disease entity can be classified as autoimmune, with modifications made in 1993 to adapt to new scientific insights.

In terms of his Human Design, Witebsky was a **Generator** with an **Emotional Inner Authority**, which suggests that he thrived on responding to the needs of his environment and making decisions based on his emotional clarity over time. His **6/2 Profile** indicates a blend of wisdom and a natural inclination towards retreat and introspection, allowing him to develop deep insights into his field. His **Incarnation Cross**, the **Left Angle Cross of Migration**, emphasizes a life path focused on transformation and adaptation, which resonates with his ability to navigate complex scientific challenges.

Witebsky’s channels, including **43-23, 15-5, 37-40, and 28-38**, reflect his unique energetic blueprint, showcasing his capacity for innovative thought and emotional resilience. He was born in Frankfurt am Main, Germany, and his legacy continues to influence the field of immunology today. He passed away on December 7, 1969, at the age of 68, leaving behind a profound impact on medical science.
