Please consider the following sentence:
Ada Lovelace is the first computer programmer in the world who wrote the code for analytical engine.
Is the placement of the relative pronoun "who" correct? Or should it be like this:
Ada Lovelace who is the first computer programmer in the world, wrote the code for analytical engine.
Should the relative pronoun come after the word that refers to it?
I think the problem isn't just the placing of a pronoun but that the sentences are unsalvageable. You could consider rewording as
Ada Lovelace wrote the code for [Babbage's] analytical engine, making her the first computer programmer in the world.
I think this question will be closed but the comments have been disabled.
So, here is the question:
"Ada Lovelace is the first computer programmer in the world who wrote the code for analytical engine.
Is the placement of the relative pronoun "who" correct? Or should it be like this:
Ada Lovelace who is the first computer programmer in the world, wrote the code for analytical engine."
There are several errors.
Ada Lovelace, the first computer programmer in the world, wrote the code for the analytical engine.
I have no idea what an analytical engine is, but it needs a determiner. And you don't need who at all. You can use an apposition.
Ada Lovelace, who wrote the code for Babbage's analytical engine, was the world's first computer programmer.
[1] Ada Lovelace was the first computer programmer in the world [who wrote the code for analytical engine]
[2] Ada Lovelace, who was the first computer programmer in the world, wrote the code for analytical engine.
The relative pronoun "who" does come after the word/phrase that it refers to.
In [1] "who" has the adjacent nominal "first computer programmer in the world" as antecedent.
In [2] "who" has the adjacent noun phrase "Ada Lovelace" as antecedent.
Since "first computer programmer in the world" refers to Ada Lovelace, there is little difference in meaning between the two other than one of emphasis.
Note the punctuation.
