TITLE: Query: Year of Death of Three Mathematicians
QUESTION [5 upvotes]: I need the year of death of the following mathematicians all of whom are written up in R.C.Archibald's book Mathematical Table Makers.
Carl Burrau, b. 1867, d. ???? - Danish, astronomer and actuary
Herbert Bristol Dwight, b. 1885, d. ???? - American, tables of integrals
Alexander John Thompson, b. 1885, d. ????, British, statistician, BAASMTC
Thanks for any insight.
Cheers, Scott

REPLY [6 votes]: Just a comment on Šiljak's source about Dwight: the footnote (in Russian) says "Год смерти этого автора точно неизвестен и оценен как 1975", i.e. the year of death of Dwight was unknown by the author of that website and "estimated" as 1975.
