Frank Albert Allack (25 September 1888[1] – 1967) was an English footballer who played as a forward for Spanish clubs RCD Espanyol and FC Barcelona.
[3] Born in Woolwich, he began to play football in England for Plumstead FC and then Catford Southend.
Allack toured Catalonia with the former, and in a match against RCD Espanyol on 18 May 1911, he put up a great performance which impressed the Catalan club enough for them to sign him, along with William Hodge and Raine Gibson.
[4][5] He had an immediate impact in Espanyol, quickly becoming one of the club's most important players and playing a pivotal role in helping his side win the 1911–12 Catalan championship, thus interrupting a three-year dominace of FC Barcelona.
His brother, Henry Thomas Allack, was also a footballer and played in Catalonia for Olot Deportiu, Sporting Club Olotí, CE Manresa and Terrassa FC.
