What does 其 mean in 授予其创意改变世界和影响今天所有人类的人? In the following sentence:


  计算机历史博物馆从1987年起每年颁发会员奖，授予其创意改变世界和影响今天所有人类的人。


The meaning would be something like the following:


  The computer history museum issues the prize from 1987, giving it to people who changed the world and made an influence on all the people.


However, I don't understand what 其 here refers to. According to a dictionary, it means "that" or "it" or "theirs" or any such demonstrative pronouns, but in this case:


其 here refers to 会员奖 and 创意 is a verb, making the sentence 授予(V)会员奖(O)人(O)
创意 is a noun, and 其 modifies 创意, making the sentence 授予(V)其创意(O)人(O)
Or anything others that I missed


Which is the correct decomposition of grammar in this sentence? And generally how should 其 be used in these cases?
其 means 他/她的 (his/her), it modifies 创意, so 其创意 means "his/her 创意".

The structure of the whole sentence is V+O, i.e. 授予(verb) + 人(object). "其创意改变世界和影响今天所有人类的" is a long modifier which modifies "人". The museum award the prize to "people", what kind of people they are? The people "whose 创意改变世界和影响今天所有人类".
