两个小单词导致的困惑

Mr.Schmidt is a baby-food veteran，having joined Nestlé in 2007 when it took over Gerber,an American maker of baby food,of which he was the boss.

本句有点看不明白，特别红色部分it和of，请教老师。

我的疑问集中在：

1、it 指代 Mr.Schmidt的话为何不需要 he？

2、是否 of which he was the boss =he was the boss of Gerber？

谢谢了！

【答】这个句子是有点困难程度。

Mr. Schmidt is a baby-food veteran，having joined Nestlé in 2007 when it took over Gerber, an American maker of baby food, of which he was the boss.

【翻译】施密特先生是婴儿食品的行家，他于2007年代理雀巢，当时雀巢回收了美国婴儿食品制造商格伯，他是该企业的老板。

1. it不可能指代Mr. Schmidt，此外，前面还出现过什么词？Nestlé（雀巢公司），自然就是它了。我在翻译时，特地用“雀巢”二字，不说“它”。

2. an American maker of baby food和Gerber（格伯公司）是同位语，一回事。那样which就是指这公司。所以，你的理解正确。
