The Whitesmiths style, also called Wishart style, to a lesser extent was originally used in the documentation for the first commercial C compiler, the Whitesmiths Compiler. It was also popular in the early days of Windows, since it was used in three influential Windows programming books, Programmer's Guide to Windows by Durant, Carlson & Yao, Programming Windows by Petzold, and Windows 3.0 Power Programming Techniques by Norton & Yao.

Pros
Pro Easy to see how blocks of code belong together.
The fact that the code lines up up with the braces makes this by far and away the easiest style to read. The code flows much more naturally, there is zero doubt about which block the codes belongs to, your eyes are quickly drawn to what belongs where.
Pro Indenting Braces removes noise from the vertical line
When scanning vertically through large sections of code to review the code execution flow, having the braces indented means less noise to filter out. The execution flow statements stand alone on the vertical line and are thus far more quickly picked out by the eye.
