There is no way that the "grandson" referenced at the end of this article can be his grandson. Christopher Vanderwal was awarded an NSF CAREER award in 2008 (https://www.faculty.uci.edu/profile.cfm?faculty_id=5265), which means he was a junior faculty member in 2008. Thus, he earned hid PhD in the early 2000s making him no more than 40-45 in 2019. That makes his birth year at best in the early to mid 1970s, which is easily 50 years after Van der Waals death and 100 years after Van der Waals marriage (in article). Even if Van der Waals celebrated the birth of his son at 75 years old (1913) that would make his son in his 60s when Christopher Vanderwal was born.
