There is no definitive answer to this question. The concept of "all countries" is subjective and can vary depending on the definition of a country. Additionally, tracking travel history, especially for individuals in the past, can be challenging.
It's important to note that the idea of traveling to every country is often associated with a pursuit of personal achievement, and there is no central organization or record-keeping system that tracks this information.
Therefore, there is no official record of who the first Black woman to visit all countries might be.
