Pupils who once lived in Blackhorse
St
Around the late 1780s it was known as Thweat St after
James Thweat (or Thweats, or Thwaites ) who built, nearby in King St
(named after George III) one of Bolton's first spinning mills.

At
that time it was only a short street, ending in a timber yard of Peter
Rothwell, with whom the young Isaac Dobson joined in partnership soon
after his arrival in Bolton in 1789, and the firm since famous as Dobson
and Barlow was founded
Isaac Dobson's first Bolton residence was at the
Black Horse Inn in Thweat St, which was then almost a suburban area.
The Inn was then a popular meeting place for the
business men of the town; so much so that it soon imposed it's name
on the street.

A
Black Horse Club was held there, to which most of the leading citizens
of the town belonged. Samuel Crompton was made a member of it when he
moved to King St.
The Dobson firm prospered and remained in the same
street until 1846 when it moved to Kay St. The premises stood till the
1930s when the new civic centre clearance scheme began.
Blackhorse St gradually developed into a street of engineering works,
but all have disappeared now. there is nothing left of what was once
one of the most important industrial areas in the town.
