"We looked at all the 3,288 articles that appeared in six [major analytic] philosophy journals between 1896 and 1960…On average, only 4%…were authored by women. Most of these women, 70 in number, are presently forgotten…Only four of the 246 papers presented at meetings of [Society for the Study of the History of Analytical Philosophy, #SSHAP] in the period 2015 to 2019 were about female philosophers – less than 2%."
