In the novella "Strange Case of Dr Jekyll and Mr Hyde", what is the first name of Mr Hyde?

"Strange Case of Dr Jekyll and Mr Hyde" is a gothic novella by Scottish author Robert Louis Stevenson, first published in 1886. The work is also known as "The Strange Case of Dr Jekyll and Mr Hyde", "Dr Jekyll and Mr Hyde", or simply "Jekyll & Hyde". It is about a London legal practitioner named Gabriel John Utterson who investigates strange occurrences between his old friend, Dr Henry Jekyll, and the evil Edward Hyde.

Dr Jekyll is a "large, well-made, smooth-faced man of fifty with something of a slyish cast", who occasionally feels he is battling between the good and evil within himself, upon leading to the struggle between his dual personalities of Henry Jekyll and Edward Hyde. He has spent a great part of his life trying to repress evil urges that were not fitting for a man of his stature.

He creates a serum, or potion, in an attempt to mask this hidden evil within his personality. However, in doing so, Jekyll transformed into the smaller, younger, cruel, remorseless, evil Hyde. Jekyll has many friends and an amiable personality, but as Hyde, he becomes mysterious and violent. As time goes by, Hyde grows in power. After taking the potion repeatedly, he no longer relies upon it to unleash his inner demon, i.e., his alter ego. Eventually, Hyde grows so strong that Jekyll becomes reliant on the potion to remain conscious.
