What one of these two Alchemists sounds the most intresting?

[Merellin]

And as a bonus question, Got any tips for how to build them? Here they come,

First one is a Human Alchemist who used to be a doctor in a small town together with his wife that worked as a nurse/assistant. He dident realy have any magic, But worked with medication and mundane means. But when a terrible illness struck the town he was helpless, No mather what he tried his knowledge couldent defeat the disease and when even his wife fell ill he started working even harder, Trying everything he could think of, Experimenting with alchemy to try and make a cure, But in the end.. He failed..

All those who fell ill, Including his wife passed away and he was devastated.. So he started working to become the best doctor in the world! Going even more into alchemy aswell to try and copy the spells some others used, He would experiment on himself and ended up going slightly crazy, And then one of his experiments caused him to get a second personality, Quite diferent form his regular one, That tries to influence him even when he is in his normal form...

He'd be a Alchemist (Dont know what archetype) With 2 or 3 levels of Master Chymist.. Dunnos how to build him..

Second is a Goblin Alchemist, He was always intelligent, If a bit odd.. One day when wandering through the swamp he discoverd the dead body of a human alchemist and proceeded to loot it for all it had! He found many strange and intresting things including a couple of books, One book contained a bunch of thought stealing words, So he burned it! And then he started experimenting with the items he had found on the alchemist and soon figured out how to make intresting things, Like things that exploded into fire!

Using the second book, That was empty, He started documenting his discoveries with crude drawings, and scented splotches while he experimented, Amazing his fellow goblins with fire and explosions! It all went quite well untill he accidently blew up the Chieftains hut, And then set it on fire.. The Chieftain was not amused and banished him from the village.. Though he dident let it keep him down and soon decided to go on a grand adventure to get ideas for new discoveries!

Realy have no idea how to make this alchemist, Other then bomb focused..

The second sounds a lot like Mogmurch from the "We Be Goblins!" module series. The first is somewhat cliche, but can definitely be taken places....

I'd give the first a shot. You definitely want the Chirgeon Archetype, which is compatible with the Reanimator, which could also fit the character well (although if you do, you should probably hold off on the Master Chymist levels, as being a Reanimator takes no fewer than 7 levels to pay off). If this is a home game, you might want to submit my suggested Reanimator "fix" for your DM's approval.

I like both concepts. As to build advice:

First one sounds like a melee/healer build. Vivisectionist/beastmorph goes good with master chymist (10 levels for pounce). Alternatively Wasteland Blighter/Chirurgeon. Discoveries are of course Feral Mutagen and maybe Spontaneous Healing/Healing Touch. Note that this is nonmagical healing (maybe the only source except Heal skill and rest?), my alchemist was the hero in a campaign where magic vanished in most of the world.

The second is also thematic, I'd definitely go with "Roll with it" and the usual bomb discoveries. Breath weapon bomb could be an alternative bomb-saving concept for a melee-er bomb build, which is compatible with being staggered from Roll with it.

If you need additional inspiration (I built both a human and a goblin alchemist as well):

The Goblin could be a great cook, mine was even very fat (can roll better) and I planned to create a Formula Book as a word document which also served as a cooking recipe collection where I'd invent some nasty Goblin meals.

The human alchemist was the son of an animal doctor. Thus I explained the beastmorph archetype, experimenting to mix human intellect and bestial strength for the greater good (resulting in a lion form mutagen). He became a Professor and his formulae book was a scientific study about anatomy of animals and magical beasts and alchemy. You see I like my formulae books versatile.

I havent looked at any of the modules (Or Adventure Paths as they appear to be called in Pathfinder) and have only played in home games in home made settings, So i dont know who Mogmurch is, But awesome! And I am bad at thinking of ideas that havent been done to death.. xD

I dont want a Vivisectionist, Way too evil feel about it, And Reanimator wouldent be too good in our current party either (We have a elf Magus who hates all undead)

I have also been trying to think of a Dwarven Alchemist, As i like Dwarves and I like Alchemists.. But I just cant get any good ideas for a Dorf Alchemist..

I have a dwarf alchemist in PFS. He's a grenadier. I have him wield a Dorn-Dergar (Dwarven Chain Flail) which he enhances with the alchemical items he makes. I made him a Slag Child (clanless dwarf) and he's got short cropped hair and no beard due to burns he received while learning to be an alchemist. He scowls at anyone who asks about it.

I think Dwarves make well rounded alchemists because your boost to Wis/Con really helps offset some of the weaknesses of being in melee in this class. The extra boosts to saves can even further be boosted with Steel Soul. Mutagen provides more than enough boost in your primary stat that it shouldn't be necessary to max out Strength or Dexterity.

I want to play an elf archer alchemist (PBS, Precise Shot, Focused Shot, Rapid Shot) with Exploding Missile (adds bomb damage to ranged weapon) that becomes a Master Chymist (Mama Bear ROWRRRR!!!), that takes Power Attack, of course.

Basically start off with ranged attacks at early levels, using Feral Mutagen for switch-hitting in emergencies, then doing more melee stuff at mid-to-late levels.

I think your goblin idea sounds more fun to play. Tragic backstories are sad, and I'm not sure how great alchemists are at healing, but they're really good at blowing things up! Bombs can be used to focus fire on one target, used to de-buff, as battlefield control, and also affect multiple targets.
