No, not only was the accepted style back then _not_ very different from
today; Einstein *did* refer to previous experiments:

| ON THE ELECTRODYNAMICS OF MOVING BODIES
| by A. Einstein
| [Annalen der Physik 17 (1905): 891-921]
|
| It is well known that Maxwell's electrodynamics – as usually understood
| at present – when applied to moving bodies, leads to asymmetries that do
| not seem to attach to the phenomena. Let us recall, for example, the
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| electrodynamic interaction between a magnet and a conductor. The
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| observable phenomenon depends here only on the relative motion of
| conductor and magnet, while according to the customary conception the two
| cases, in which, respectively, either the one or the other of the two
| bodies is the one in motion, are to be strictly differentiated from each
| other. For if the magnet is in motion and the conductor is at rest, there
| arises in the surroundings of the magnet an electric field endowed with a
| certain energy value that produces a current in the places where parts of
| the conductor are located. But if the magnet is at rest and the conductor
| is in motion, no electric field arises in the surroundings of the magnet,
| while in the conductor an electromotive force will arise, to which in
| itself there does not correspond any energy, but which, provided that the
| relative motion in the two cases considered is the same, gives rise to
| electrical currents that have the same magnitude and the same course as
| those produced by the electric forces in the first-mentioned case.
|
| Examples of a similar kind, and the failure of attempts to detect a
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| motion of the earth relative to the "light medium", lead to the conjecture
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| that not only in mechanics, but in electrodynamics as well, the phenomena
| do not have any properties corresponding to the concept of absolute rest,
| but that in all coordinate systems in which the mechanical equations are
| valid, also the same electrodynamic and optical laws are valid, as has
| already been shown for quantities of the first order. […]

(see the margin notes in the translation for details)
Einstein’s paper “On the Electrodynamics of Moving Bodies” (1905) *is*
different to others because “he [had] answered a question no-one was
asking”. Also, Einstein did have a singular writing style. (See also
National Geographic, “Genius”, episode 4.)
