famous mathematician, died suddenly after an operation July 17, 1912 query.nytimes.com/mem/archive-free/pdf?_r=1&res=9D01E...

I think it is the statesman, who would have been 53 in 1913 when he was elected the President of France: en.wikipedia.org/wiki/Raymond_Poincar%c3%a9

ah you mean his cousin, Raymomd, the photo more resembles him so yes, quite the family President of France from 1913 to 1920. Henri himself was only 58 when he died so he could not have been Raymond's father :) en.wikipedia.org/wiki/Raymond_Poincar%c3%a9

Evidently the invitation to visit Spain was reciprocation for Poincare's earlier hospitality to Alfonso in Paris:

Another Bain/LOC copy of the photo of Poincare and Alfonso in Spain:

Alfonso XIII (Alfonso León Fernando María Jaime Isidro Pascual Antonio de Borbón y Austria-Lorena; 17 May 1886 – 28 February 1941) was King of Spain from 1886 until 1931. His mother, Maria Christina of Austria, was appointed regent during his minority. In 1902, on attaining his 16th year, the King assumed control of the state. en.wikipedia.org/wiki/Alfonso_XIII_of_Spain Alfonso, Prince of Asturias (Alfonso Pío Cristino Eduardo Francisco Guillermo Carlos Enrique Eugenio Fernando Antonio Venancio Borbón y Battenberg (Madrid, 10 May 1907 – Miami, Miami-Dade County, Florida, 6 September 1938), was an Infante of Spain and the heir-apparent of the throne of Spain from 1907 to 1931. en.wikipedia.org/wiki/Alfonso,_Prince_of_Asturias_(1907-1938)
