Here's something else you've got wrong. You've already been corrected about slavery, but I also object to the way you have written out of history the huge contribution of migrant Irish workers to the building not just of Brunel's structures, but vast amounts of the UK's infrastructure.
Brunel Museum Shines A Light On The Irish Workers Who Built The Thames Tunnel | Londonist
There's even a contemporaneous funny song called The Humours of Whiskey that mentions Brunel:
And what helped Mr. Brunnell to build the Thames Tunnel
Wasn't it poteen from ould Inisowen
and the more recent Building up and tearing England down:
But the likes of you and me will never get the O.B.E
Or a knighthood for good service to the hod
It's the concrete master race
That would keep you in your place
And a ganger man to kick you to the ground
If you ever try to take part of what the bosses made
When you're building up and tearing England down.
and McAlpine's Fusiliers:
I've worked till the sweat near had me bet
With Russian, Czech and Pole
At shuttering jams up in the Hydro Dams
or underneath the Thames in a hole
I grafted hard and I got me cards
and many a ganger's fist across me ears
If you pride your life, don't join, by Christ, with McAlpine's Fusiliers.
Is that enough evidence, GiddyGiddyGiddy, for you to amend your claim about who it was who 'helped Mr Brunnel to build the Thames Tunnel' etc and correct the record about the huge role of Irish workers in 'building up and tearing England down'?
