PROVENANCE AND HISTORY OF THE COLLECTION
The material was received in several instalments and from several —

CAREER AND WORK OF E.V. APPLETON
Born in Bradford in 1892 of modest origins, Appleton became
one of the pioneers of ionospheric research and an important figure in scientific and
public life in Britain.
After education in primary and secondary schools in Bradford,
Appleton won a scholarship to St. John's College, Cambridge, where he was awarded
first-class honours and several prizes in both parts of the Tripos (1913, 1914).
He began
research at the Cavendish Laboratory with Lawrence Bragg, but during his service in
with B. van der Pol, on non-linearity, and on atmospherics.
In 1924, in collaboration
in the atmosphere to be identified and measured; subsequent research indicated the
‘wireless' signals which informed his subsequent research career.
He returned to
Cambridge and the Cavendish Laboratory in 1919, continuing to work on valves and,

with M.F. Barnett,
he performed a crucial experiment which enabled a reflecting layer
collaborative research on many ionospheric problems, including solar and lunor tides
directing research teams and, in 1932, heading an expedition to Troms in northern
Norway as part of the programme of observations scheduled for the Second Polar Year.
He was elected Fellow of the Royal Society in 1927, and was President of the Inter-
Wilson in the Jacksonian Chair of Natural Philosophy at Cambridge, where he continued
national Union of Scientific Radio (U.R.S.1.) 1934-52.
In 1936 he succeeded C.T.R.
to 1936 Appleton was Wheatstone Professor of Physics at King's College, London,

from September 1936 he served on the freshly re-constituted Committee for
the Scientific Survey of Air Defence (the 'Tizard Committee').
accepted appointment as successor to Sir Frank Smith as Secretary to the Department of
Scientific and Industrial Research, where he remained throughout the Second World War
(he was made K.C.B. in 1941) and until 1948 when he was appointed Principal of Edin-
burgh University.
He took up the appointment in May 1949 and remained in office
In October 1938 he
until his sudden death in 1965.
He was twice married.
Although Appleton's career from 1938 was passed primarily in
administration, he never lost his interest in ionospheric research.
During his tenure of
the Secretaryship of the D.S.1.R., he kept up his contacts with the Radio Research
Board and with individual colleagues such as R. Naismith and W.R. Piggott;
his position
in U.R.S.1. kept him in touch with data and research in progress at observatories through-
out the world; and, though he had no laboratory or research department at Edinburgh as
he had initially hoped might be the case, he worked with a succession of assistants and
with the famous 'lonospheric Young Ladies' - mathematical students - to maintain a
steady output of research papers right to the end.
Clark, Sir Edward Appleton, p.217,
mentions 87 papers produced from Edinburgh, and many biographical accounts of Appleton
conferences and discussions.

collaborative work and correspondence from colleagues.
Section A contains the sur-
viving material relating to Appleton's career, though it

record.
There is, however, a good run of diaries and engagement books, and these,
together with the scientific notebooks in Section B, comprise the legendary - not to say
mythical - ‘little black books' which Appleton always carried with him to record his
past, present and future activities.
The main documentation of Appleton's scientific research is
in
Section C.
The considerable time-lapse already alluded to between Appleton's death
and the receipt of the papers, and the fact that they had had to be moved several times,
added greatly to the problems of sorting.
Very few of Appleton's own named folders
survived, and they were so crammed with material that it was thought best to divide the
papers into more manageable units while preserving the original folder and title or
description.
Most of the material, however, was received as loose papers.
Appleton's
handwriting was fine and showed little variation, at least until the arrival of the ballpoint
pen;
he very rarely dated his notes and although he would sometimes give them a heading
he usually had several research projects in hand simultaneously and would refer to more
than one phenomenon or theory in the course of each sequence of notes.

SECTION B
SCIENTIFIC NOTEBOOKS _ B.1 - B.60
These books have a twofold origin.
Some are laboratory notebooks
in the usual sense, documenting experimental work with dates and descriptions, and
sometimes kept partly by research assistants and collaborators as well as by Appleton
himself.
Others are more diverse, and belong to the category of ‘little black
books'.
Appleton's lifelong habit of keeping small notebooks in his pockets was well
known and commented on by his biographers, who often quote from them.
The description
‘little black books' is clearly no more than a generic term, since very few are black and
some are quite large.
Nevertheless they have many features in common; few are dated,
and Appleton seems to have kept several of them in play at the same time so that each
book might remain in sporadic use for years, entries being made at the front, back, or
on odd blank pages in the middle.
Conversely, certain books are hardly used at all.
The content is heterogeneous and includes notes for experiments to be performed, theories
to be tested or papers to be written, diagrams, calculations and 'thinking aloud', notes
on the literature, of lectures or discussions at conferences, of points to be raised at
speeches or writings - not all of them on scientific subjects.
To a small extent, the material is similar to the diaries in Section A,
end of the sequence (B.48 - B.57).
or general topics with no details of engagements or chronology.
Dated material, or that to which a date can be tentatively assigned
on internal evidence, is presented as a sequence.
Undated material is placed at the

meetings, quotations, anecdotes, epigrams or longer paragraphs for inclusion in Appleton's

Attention is drawn to B.58 - B.60, which comprise two bound volumes and one
folder of press-cuttings recording developments in 'wireless', radio and television.

what less methodically until about 1939.

INTRODUCTION TO SECTION C
The material in this Section is very diverse.
It includes notes and
ideas by Appleton, comments and suggestions exchanged with research assistants, collaborators
and colleagues, drafts for discussion meetings or for papers and talks, data (charts, graphs,
diagrams) and correspondence.
The alphabetical sequence in which the material is presented is
intended as no more than a guide.
Some of the titles, such as 'Absorption', 'Atmospheric
Spectrum', 'lonized Air', 'Recombination and attachment', 'B - determinations', etc.
correspond to Appleton's own file-headings, but others were adopted for the purpose of this
catalogue on the advice of scientists and historians of science.

material andtime.
this is frequently tentative; undated papers come at the end of each sequence.
Within each topic, the papers are in a chronological sequence, though
In some cases, the headings
A very substantial proportion of the material was received as loose
papers, rarely dated by Appleton and showing little variation in his handwriting over the
years which might have permitted closer dating.
Although efforts have been made, and
advice taken, to assign work to some identified field of study or period of time, it has not
always been possible to do so with any certainty.
Material of this kind has been grouped
under the title 'General lonospheric Topics' (C.106 - C.165).
collaborative work undertaken during Appleton's service as Principal of Edinburgh University
1949-65, when he pursued several lines of enquiry simultaneously with the help of a series
of assistants and colleagues at Edinburgh (particularly Mrs. A.G. Pritchard, later Turnbull,
A.J. lyon, C.P. Bell, and the 'lonospheric Young Ladies' from the Department of Mathe-
matics) as well as postal discussion with his lifelong colleagues W.R. Piggott, and W.J.G.
(later Sir Granville) Beynon.

consist only of material either specifically related to the topic in hand, or kept in a named
folder by Appleton himself.

Section F contains extensive additional data, prepared by or under
the direction of Appleton in the furtherance of various research projects.
Section G
includes data and reports sent to him from observatories and ionospheric stations worldwide.
These Sections should therefore be regarded as
supplementary to Section C.
In addition,
the notebooks in Section B often provide the embryo of Appleton's research ideas.

Research topics
Drafts, notes, data, correspondence.
Much of this material was originally crammed into a folder
inscribed 'Abnormal E Paper', with a ms. note added later
by Appleton 'Mr. Lyon to see.
These are approx. 20 year-
old notes! '
The bulk of the material refers to work in the 1930s, including
Appleton's collaborative papers with R. Naismith and L. J.
Ingram (C.36-C.45).
The later folders (C.46-C.50) refer to his work in the 1950s
with A.J. Lyon and A. G. Pritchard and to his last article
on the subject, which was unfinished at his death (C.50).
Additional data, notes, etc. dealing with various research
projects on the 'E Layer' but not included with this specific
material, can be found in 'General lonospheric Topics’ in
Section F.
Correspondence on E-layer research appears at C.51-C.55.
Notes and drafts for Appleton's last paper on the E-layer,
unfinished at his death, are at D.62-D. 64.

U.R.S.1.
(International Union of Scientific Radio)
Appleton attended and contributed papers to the meetings of U.R.S.1.
from 1927, when he announced his discovery of the F layer at the Second General Assembly
in Washington (C.361).
He was President of the Union 1934 - 52, and also Chairman of
the Mixed Commission on the lonosphere (M.C.1.).
The Fourth General Assembly of U.R.S.1. at Copenhagen, to which
Appleton contributed a paper on ‘Some Observations on International Research on Atmospherics'
(C.361), decided to organise a Sub-Committee to conduct radio observations during the
Second Polar Year 1932 - 33.
Appleton was Chairman of this Sub-Committee and the
observations were made at Tromst in northern Norway.
See C.304 - C.322 for his journals
and photographs of the expedition and correspondence before and after the trip, with
colleagues and collaborators on the interpretation and publication of the data.
After the Second World War, Appleton, as President of U.R.S.1.
and Chairman of M.C.1., helped to organise and attended many of the international
finally held in 1957 - 58, and Appleton helped to foster the preparations.
The material, which runs 1927 - 60,
is presented chronologically
and is of varied nature, correspondence, research reports and data, arrangements for

1920-54
Van der Pol was the first of Appleton's close
colloborators, their friendship beginning at the
Cavendish Laboratory in 1919.
Later that year, Van der
Pol returned to the Netherlands to work in Haarlem under
H.A. Lorentz;
of posts at Delft and (via Appleton) at Cambridge, he
accepted (June 1922) a position in the Research Department
of N.V. Philips Gloeilampenfabrieken, Eindhoven.

The correspondence tails off
There was
The correspondence is particularly intensive, 1921-24, and
is primarily concerned with work on oscillations and non-
linearity.
From the surviving evidence, Appleton was the
more assiduous correspondent, writing letters and postcards
from his laboratory, his home and from various holiday addresses,
sometimes more than once a day when a thought, or a second
thought, struck him.
Although the letters are almost wholly
‘ concerned with research problems, there are a few personal
references to family matters, occasional visits, Cambridge
affairs and personalities, etc.

friendly, fashion after the Second World War.
@ somewhat sharp exchange in 1927 (E.132, E.144) when
Appleton thought that his proposed election to the Royal
Society might be jeopardised by references to his work in an
article published by Van der Pol, but all was well and the
friendly tone of the correspondence resumed undiminished.

No doubt as a result of previous interest in the letters, some
degree of sorting and numbering had already been carried
out, which has imposed constraints on the present listing.

INTRODUCTION TO SECTION F
Charts, graphs, data
The material in this Section is entirely manuscript.
It was
prepared under Appleton's instructions by collaborators, students and assistants, mainly
1949 - 65, for various research projects on the ionosphere.
Some of the charts are in
identifiable hands such as those of A.J. Lyon and A.G. Pritchard (later Turnbull) but
the majority seem to have been compiled by the 'lonospheric Young Ladies'.
There
is an occasional note in Appleton's own hand.
Some of the material remains in
its origina] folders or wrappers,
but most was received as loose sheets.
It constitutes the background information for the
various projects in Section C, and which, because of its bulk and because it
is not
specifically referred to in correspondence or drafts, has been listed separately.
The contents are very miscellaneous.
The index covers only
broad descriptive titles;
any original groupings or headings have been preserved and
are indicated by the use of inverted commas, but it has not been possible to furnish
