We have already seen that John Goodall took the original lease in 1864, had been an Assistant Master, and was a writer.  In fact, the earlier 1871 Census describes him as a "Civil Service Clerk in the Office of Education", with, in smaller handwriting below, the words "and author" squeezed in.   As shown in the extract above, he had written some pieces on Dulwich itself.  He had also authored the entry on Edward Alleyn for Encyclopaedia Britannica.

More significantly, he was one of the authors in a four part history "The National History of England:  Civil, Military, Domestic", published in 1868 -1877.  The book was very ambitious, spanning Roman times through to 1874.  It covered, for each period: civil and military history; law and government; religion; literature, science and art; industry and commerce; and manners customs and social condition and "upwards of 500 engravings illustrative of antiquities, customs, scenery, manners and customs".

The British Library kindly ordered the original volumes for me:  large, heavy leather-bound volumes, numbering over 2,000 pages in total.  The book is weighty in every sense.  The authors were well-respected writers of books on education, history and banking and the introduction was written by Lord Brougham (Lord Chancellor from 1830-34).  John Goodall's contribution to this writing "collective" was to author a number of the chapters in Volumes III and in IV, published in the 1870s.  He covered all aspects of the Stuarts, William and Mary and Ann, the House of Hanover and the reign of Victoria.  His chapter on Charles II starts:
"The restoration of kingly government, in the person of Charles II, was hailed throughout the land with the most exuberant demonstration of delight....  .... A recent bitter experience has taught them to hate the misrule and military oppression of military despotism and the legislation of gloomy fanatics…"
Clearly, not a fan of Oliver Cromwell, then.  Little did John Goodall know who would be living next door to him a few years later!

One of the Goodall sons, Thomas Frederick, also achieved some notoriety.  He was an artist, who painted using the name "T.F. Goodall". The use of "T.F." was, perhaps, so as not to be confused with a contemporary (slightly better-known) artist, Frederick Goodall, R.A. – although T.F. Goodall was a student at the Royal Academy.  He joined as a "probationer" in July 1873, became an RA student on 17 January 1874, at the age of 17, and exhibited fifteen paintings at the Royal Academy between 1879 and 1901. Having seen where T.F. Goodall grew up, it is perhaps no surprise that he focused on landscapes, described as one of the English impressionists. 

He would be associated with other great artists from the age and, along with Walter Sickert, John McNeill Whistler, John Singer Sargent and others (including former schoolmates, Henry La Thangue and Stanhope Forbes), Thomas Goodall was also a founder-member of the New English Art Club, in 1886, which broke away from the Royal Academy, in protest at its "stuffiness".

T.F. Goodall also illustrated "The Order for Morning and Evening Prayer, Litany, and Occasional Prayers, Illustrated with Floral and other Ornamental Borders in Coloured Outline", in 1873, assisting Walter Severn, when T.F. Goodall would have only been 16 or 17 years old.  Later, he worked alongside Peter Emerson, a photographer, to co-author a book "Life and Landscape on the Norfolk Broads", in 1887, in which T.F. Goodall wrote a chapter on landscape. In 2013, an original of this rare book of photographs sold at auction for £66,000.

Arthur Hammond Goodall, the youngest son, was a photographer.  Some of his photos from 1888 (when 18 years old) are stored in the national archives at Kew – including a photo of the Primrose League "Baumann Habitation" meeting in Peckham.
