The story of the word

Friedrich Hopff, working under Schönlein at Zurich, published Hämophilie in 1828 for a bleeding tendency that rabbinical and medical texts had been describing for centuries. The name is a poor one and physicians have said so ever since, because φιλία means affection or affinity, so the word promises a fondness for blood rather than an inability to keep it in. The suffix was meant in its weaker sense of a tendency towards something, the same shading that survives in hydrophilic.
