François Hennébique

Died 20 Mar 1921 at age 78 (born 25 Apr 1842).French engineer who was an important leader in experimenting with various ways of reinforcing concrete with iron and steel. At the Paris Exposition of 1867, Hennebique saw Joseph Monier's tubs and tanks built of concrete reinforced with wire mesh, and began experimenting with ways to apply this new material to building construction, setting up his own firm (1867). First using reinforced-concrete floor slabs (1879), he progressed to a complete building system, patented 1892, using his invention of a method using hooked connections on reinforcing bars. Hennébique introduced his techniques into Britain when he was commissioned to build a new flour mill in Swansea (completed 1898). This was the first multistorey reinforced concrete building in Britain.

Sibling lessons

Charlie was playing with his little brother Mickey when the little boy asked whether he could fly like Superman.

"Sure you can, Mickey," Charlie said, "Just flap your arms really *really* hard."

So Mickey climbed up on the windowsill, started flapping like mad, jumped, then smashed into the ground two stories below.

Horrified, their mother came screaming into the room and said, "What the heck happened?!?"

Charlie said, "I was just teaching Mickey not to believe everything someone tells him."
