Who was the first person who bombed Archduke Franz Ferdinand?

The first person who attempted to assassinate Archduke Franz Ferdinand was Nedeljko Cabrinovic, a Bosnian Serb nationalist. On June 28, 1914, he threw a hand grenade at the Archduke's motorcade in Sarajevo, but missed, injuring others instead. Later that day, Cabrinovic attempted to take his own life by swallowing a cyanide pill, which failed, leading to his capture. The assassination attempt ultimately contributed to the outbreak of World War I.
