The French chemist Antoine Lavoisier (1743-1794) was the first to
formulate a law of conservation of matter in chemical reactions. The
concept of inter-conversion of mass and energy has been studied by
various scientists qualitatively, even before Einstein.
1. Newton has quoted in his book ‘Opticks’ in 1704 that
"Gross bodies and light are convertible into one another...",
After about 200 years Einstein derived mathematical equation for
Newton’s perception i.e. ∆L =∆mc2 where ∆L is light energy
emitted when mass ∆m is annihilated and is speed of light. It is
the rarest coincidence in between Newton’s hypothesis and
Einstein’s mathematical derivation.
2. S. Tolver Preston proposed that a vast amount of energy can be
produced from matter in his book Physics of the Ether in 1875.
Preston determined that one grain could lift a 100,000-ton object up to
a height of 1.9 miles. This deduction yields dE  dmc2.
3. Jules Henri Poincaré in 1900 applied the calculations in a
recoil process and reached at the conclusion in the form, mv = (E/c2)c.
From the viewpoint of dimensional analysis, E/c2 takes on the role of
a ‘mass’ associated with radiation, which yields E=mc2.
4. Olinto De Pretto speculated E=mc2, implying that when v=c , then
E= mv2 becomes E=mc2 , in 1903-04. But Pretto neither gave
specific derivation nor mathematical calculations. Bartocci claimed
that Einstein was aware of De Pretto’s speculation of E=∆mc2 ,
which was published about a year before.
5. Fritz Hasenohrl in 1904, concluded: “to the mechanical mass
of our system must be added an apparent mass which is given by,
m=8E/3c2 where E is the energy of the radiation.” In a later paper
he further improved result that mass exchanged is, m=4E/3c2. Ebenezer
Cunningham in 1914 in the book The Principles of Relativity showed that
F. Hasenöhrl, had made a slight error in his calculations. If errors
are removed then the mass exchanged is m =E/c2 or E = mc2. Thus in this
regard Hasenohrl’s contribution is the most significant, before
Einstein.
6. Frederick Soddi and M. Henri Becquerel both have predicted that in
radioactive emissions the mass of body decreases i.e. energy of
radiations is at the cost of mass.
7. Max Planck in 1907 made an in-depth investigation of the energy
"confined" within a body, but he did not use Einstein’s approach at
all. Planck derived an expression m-M= E/c2, for heat energy and mass
and interpreted that
” The inertia mass of body is altered by absorption or emission of
heat energy. The increments of mass of body are equal to heat energy
divided by square of speed of light.”
Planck acknowledged Einstein’s previous derivation but did not agree
with correctness of Einstein’s derivation.
Should these scientists be given credit of doing basic work in
assisting the discovery of E=mc2 ?
Today, E=mc2 is regarded a sole province of Einstein.

If some scientists is left , please add. I think one is JJ Thomson

The facts discussed /pointed out by all of you are true.

Here I posted a very limited discussion. Single question.

WHO INVENTED/SUGGESTED E=mc2 ( mass energy interconversion equation
first of all )?

It is such a significant equation in science. It origin must be
actually known I have discuused from days og Newton to till date.

When E=mc2 was derived?
Which is the most original paper?
The answer to his question is
A.Einstein, Annalen der Physik 18 (1905) 639-641.
. DOES THE INERTIA OF A BODY DEPEND
UPON ITS ENERGY-CONTENT?
Weblink is
Einstein’s 27 Sep 1905 paper available at
http://www.fourmilab.ch/etexts/einstein/E_mc2/www/

Under what conditions E=mc2 was derived ?
What are limitations of the derivation ?
What could be next form of E=mc2?
All these things are discussed in my book. With availability of
INTERNET, all things became easier.

People are realising the truths now.

When will you catch on? The number and depth of the flaws in your
material is breathtaking. Once again YOU HAVE NEVER PUBLISHED A SINGLE
PAPER ON YOUR SO CALLED THEORY. There is not a single peer-reviewed
article in a physics journal in your list of "papers" YOU HAVE ONLY
CONFERENCES THAT ACCEPT ANY PAPER FROM ANY AUTHOR ON ANY SUBJECT. Try
using the scientific method.

When will you catch on idiot?
Einstein was a plagiarist, big time!

Einstein was a not just a Jew, but a Zionist. He was even offered the Presidency of Israel, that's why Einstein was made to be God of science, an icon of Israel.
Einstein first wife was a smart scientist, during the marriage Einstein had the most productive years, all though later her name was erased every where. Even her grave today is just grown over weeds in Switzerland , headstone removed.
Jews wants her out of the picture, big time.
PBS run a documentary about it few weeks ago.
