The 'classic' VSF authors, apart from Wells, are probably Jules Verne (20,000 Leagues Under the Sea, Voyage to the Centre of the Earth, From the Earth to the Moon and sequels) and Edgar Rice Burroughs (Princess of Mars and sequels). Add Arthur Conan Doyle (Sherlock Holmes), Anthony Hope (Prsoner of Zenda and sequels, as well as other authors writing 'Ruritanian' or 'Graustarkian' adventure-romances) and H Rider Haggard (King Solomon's Mines and sequels) to taste.
In fact, Captain Nemo, Allan Quatermain and Sherlock Holmes travelling to Mars via Ruritania to intervene in the war between the Tripods and the Barsoomians is pretty much how we do things round here - with side-orders of the Dear Old Queen, Gawd Bless 'er, blowing the heads off zombies.
For the last one, you have to go for more modern authors such as AE Moorat ('Queen Victoria: Demon Hunter'). At that point you might want to check out people like Philp Reeve ('Mortal Engines'), Kenneth Oppel ('Airborn'), Cherie Priest ('Boneshaker') and Chris Wooding ('Retribution Falls'), who write adventurous stories of people in airships and such like (not exactly VSF per se, more like steampunk if that's a valid distinction for you). 'The League of Extraordinary Gentlemen' is another reference point.
It may strike you that in fact, the 'VSF' writers are either not 'Victorian' so much (HG Wells, Edgar Rice Burroughs), not writing in English (Jules Verne), or not really writing sci-fi (Anthony Hope, H Rider Haggard, Arthur Conan Doyle). But that doesn't matter, it's all a big mish-mash. Personally I think if it's got airships in it that's good enough for me.
