It is astounding to me that the discovery of humans having 46 chromosomes is younger than I am. How could we have uncovered this truth so recently? Perhaps I am older than I feel? I suspect each of us working in genetics has some paper or lecture which frames our recognition that looking for scientific truth is a never-ending pursuit. It wasn’t until I was a faculty member that I realized professors at their most definitive are likely to be proven over time to be somewhat wrong. I have also come to know that “getting the math right” continues to underlie a lot of what we do in medical genetics and genetic counseling. My chosen defining moment occurred when I sat in a small crowded National Institutes of Health (NIH) office in 1978, interviewing Dr. J-H Tjio, the man who first counted 46 chromosomes under the microscope (Harper 2006; Tjio and Levan 1956).
