The spanning-tree algorithm is used to prevent bridging loops by
creating a spanning tree of bridges such that there is only one
path between any pair of LANs on the network.
The spanning-tree algorithm was developed by Digital Equipment
Corporation (Digital) to preserve the benefits of loops, while
eliminating their problems.

Standards
Digital's spanning tree implementation was revised by the
Institute of Electrical and Electronic Engineers (IEEE) and came
to be known as IEEE's 802.1d spanning-tree algorithm.
The IEEE 802.1d and Digital's spanning-tree implementations are
not compatible with one another.

No, as per the above.

You'd probably have to read the documentation for your networking
equipment to see which protocol it uses. I am not an expert on this
(which means "if you reply to this message and send the reply only to
me, not to the list, you're making a mistake"), but I have the
impression - possibly incorrect - that only some lines of DEC networking
equipment used the DEC version rather than the IEEE version.

As far as I know, it's just the protocol developed by DEC.
