Eminent trader, public figure, donor; participant in the national liberation movement. He himself funded the construction of the old building of St Trinity School in Plovdiv, and later became its permanent donor. The notes in his personal pocket notebook, kept in a museum today, show information about other donations of his for other Plovdiv schools: the Big School, the Girls School, the one in the Gulbahcha neighborhood...

He was a member of the secret Revolutionary Committee, created by Vassil Levski, back in 1869. After the brutal defeat of the 1876 April Uprising, Dusho Hadjidekov was imprisoned, and after two years at the Tash Kapia prison in Plovdiv, he was slaughtered by the Turkish soldiers together with another 122 prisoners just hours before the liberation of Plovdiv.

At the place where the Bulgarian prisoners got murdered today stands a monument - a large metal cross and a memorial plate, honoring the 123 victims.
