In 1803, Otto published a paper titled "An Account of an Hemorrhagic Disposition Existing in Certain Families," in which he described the hereditary nature of hemophilia. He noted that the condition primarily affected males and was passed down through female carriers. Otto's work laid the foundation for future research on the genetic basis of hemophilia and its transmission patterns.
