Hibam?
It's a typo, it's supposed to be Hiram.
But it's not the machinegun Hiram, it's his son.
http://en.wikipedia.org/wiki/Hiram_Percy_MaximHe was the son of Sir Hiram Stevens Maxim, inventor of the Maxim Machine gun. In addition, he was the nephew of Hudson Maxim, an inventor of explosives and ballistic propellants. He had two sisters, Florence Maxim, who married George Albert Cutter, and Adelaide Maxim, who married Eldon Joubert, Ignace Paderewski's piano tuner.[1] Hiram was a mechanical engineering graduate, class of 1886, of the Massachusetts Institute of Technology (then a two-year course).
