This is an annex to the Index of Mathematicians. The following entries in that index are elusive on the web as people however ubiquitous
and important their mathematical work. If you know of a link that I could use in
my Index I would be greatful
to hear of it. Better still, offer an article to the MacTutor History of Mathematics Archive or to Wikipedia,
so that everyone may benefit.
He was a student of James Alexander according to the latter's genealogy, being award his PhD in 1927. He was elected to AMS membership in February 1922.
He 'belongs' to Sebrell, Southampton county, Virginia, according to this 1925 Princeton yearbook entry. His dates may be 1894–1959 see here, entry 823 and here. Internet searches for his details are hampered by his name being shared with
a character in Twin Peaks.
Was awarded a PhD in 1953 at University of Minnesota for a dissertation entitled "Certain probability limit theorems and transformations of stochastic processes." There is a record at p. 220 here (7MB pdf) of his being promoted in 1951 from Teaching Assistant to Research Assistant, with a salary rise from $810 to $1215.
Known for his 1950 publication "Su una presumibile proprietà caratteristica dei numeri primi",Ist. Lombardo Sci. Lett. Cl. Sci. Mat. Nat. Rend. (3) 14 (1950), 511–528. More on the journal may be found here.
Graduated from Tinity College Cambridge, 3rd Wrangler, 1883, 1st Division in Part III., 1884. Then Smith's prizewinner (one A.N. Whitehead was a runner-up!) (Nature 33, 93-93, 26 November 1885), at which time he was a mathematics
instructor at the Royal Naval College, Greenwich, then returning to Cambridge as a coach in 1899 ("Geometry at Cambridge, 1863–1940",
June Barrow-Green, Jeremy Gray, Historia Mathematica, vol. 33, (3), 315-356). Published his work on systems of circles in 1886 (Proc. Royal Soc.). Contributed to a book on mathematics of map making by Gerald Maxwell which was (unfavourably) reviewed in The Geographical Journal, Vol. 48, No. 2 (Aug., 1916), pp. 168-170. June Barrow-Green has alerted me to a fairly complete record in the Alumni Cantabrigiensis. There is also a short tribute to him at findagrave.com.
Probably the soldier whose 1915 death at the age of 59 is recorded here (29MB pdf, see p. 130). Since he died in mid-November his birth was most likely in 1856, and this is confirmed by internet search (but not in a citable form).
Emeritus at University of California Santa Barbara who offer, however, no information upon him. A biographical article by Marvin Marcus appeared in Linear and Multilinear Algebra in 2003. An obituary is here and an autobiographical article.
Presumably not the educationalist who was working at the same time. There was a chemist of this name also active and it is plausible that a chemist might have published on tilings. However, the original article by Robin in La Nature is categorised under "Variétés. -- Généralités. -- Statistique" rather than "Chimie". The article is available online but gives no affilliation.
His entry at math genealogy. Taught at University of Alaska Anchorage, where a scholarhip bears his name. He retired in 2010 (Matters Mathematical report by Hans Nordstrom, Seattle Meeting, April 9-10, 2010, online as rtf file).
Willans' formula for π(n) was published in 1964 from "The University, Birmingham". Some thorough but inconclusive research by MrDannyDetail is posted in the comments to this nice
Eric Rowland Youtube video on Willan's formula. This finds a Christopher Paul Willans whose birth is registered in 1942 Bradford and who most probably matches a death registered in 1971 in Bradford of a Christopher Paul Willans who was born 17th January 1942. This would suggest the formula was the work of a postgraduate who then died tragically young and, from MrDannyDetail's research, with neither issue nor siblings. Thanks to Arthur Newlands (twitter @ArthurNewlands) for telling me about this. Further corroboration has been provided by Neil Howell who found an entry in the Shipley Times and Express, 17th September, 1958, recording 'O'-level passes for a C.P. Willans in scripture, English language, English literature and French (but no mention of mathematics). The image is followed by the result of Neil's further enquries.
Thank you for your recent enquiry regarding C. P. Willans. Having checked the class list records, I can confirm that he attended Bradford Grammar School from 1953 until 1959. Unfortunately I’ve been unable to find any further information regarding his mathematical ability or his study destination after leaving the school.

These investigations seem conclusive enough to record his name and dates in his Mathematicians listing (but insufficient, one would say, for the creation of a Wiki entry).
