His Lordship Alfredo Augusto das Neves Holtreman,^[1] Viscount of Alvalade, was a Portuguese lawyer, land tenant, businessman and philanthropist.^[2] He was the first president of Sporting CP, from 1906 to 1910, sports club founded in 1906 by his grandson José Alvalade through the Viscount's donation of money and land.^[3][4][5]

Alfredo Holtreman graduated from the University of Coimbra Law School being awarded a Bachelor of Law degree and settled in Lisbon since one of the family's farms was in Lumiar, becoming one of the most prestigious lawyers in the Portuguese capital along the way. As a lawyer, he worked for the royal household of the Kingdom of Portugal.^[4] In 1859, he married D. Julieta Natalina Luiza Guerin, of whom he had two daughters, one of them mother of José Alfredo Holtreman Roquette (widely known as José Alvalade), future promoter of the birth of Sporting Clube de Portugal (Sporting CP).

On 22 July 1898, he was graced by King D. Carlos with the title of 1st Viscount of Alvalade. He was a very cheerful man who encouraged his grandchildren, whom he liked to see gathered in his mansion, in intense activity with other young people. That was how José remembered his grandfather when he decided to found a great club and asked for money. This one did not hesitate and it advanced to him 200,000 reis, making available a piece of land of his farm for the construction of the sporting and social facilities of the new club, that became known as Sítio das Mouras. He was immediately declared a protective partner and was elected the first president of Sporting, functions that would stop on 4 January 1910, happening then to preside to the General Assembly until 28 July 1917.

In 1907, he wrote the first statutes of Sporting CP, being declared Titular Partner of the Club in 1910 and Member of Honor in 1912. By the time he died in 1920 he had already left the Club, discouraged by the premature death of his grandson José Alvalade who had been a victim of the pneumonic epidemic in October 1918.^[6]

On 30 June 2017, he was posthumously awarded the Lions Honoris Sporting award in the Honor Class category.

Alfredo Holtreman had a relationship with an underage mistress with whom he had a son out of wedlock and married to a maid two weeks before his death.^[7]
