Origin of the street name Reclaimation Street in Mong Kok

What is the origin of the street name Reclaimation Street. Was it part of the harbour 100 years ago? Judging from an old map, Nathan Road was only two streets from the harbour. If you look at the north-south streets between Gascoigne Road and Jordan Road in Yau Ma Tei on a modern map, you will see the layouts of those streets are different from the streets to the north and south.  It appeared that the land between Gascoigne Road, Jordan Road, and Nathan Road was there before the reclaimation started.

I like to know more about land reclaimation in Hong Kong between the middle of 19th century and 1960's. Perhaps some old photos and maps. I also like to know more about the Kai Tak Bund project, and the modern location of it. Thanks.
