Who's Who at 19th Century Geological Maps, Books and Illustrations

Annie and John Henry

John and Annie Henry began 19th Century geological maps in 1994.

John is a semi-retired consulting geologist working mainly in construction through his business APIC - Air Photo Interpretation Consultancy. He is a graduate of the University of Waterloo, Canada and of ITC, Enschede, Netherlands. From 1973 to 2003, he worked in Arup Geotechnics. There, he established the air photo section and was responsible for engineering desk studies. In this role he established a large corporate map and air photo collection, and carried out fieldwork for highway, railway and pipeline projects in the UK and Ireland and overseas in the Mediterranean, sub-Saharan Africa, Saudi Arabia, east Asia and Australia.

'Overseas' work included projects Tunisia, Libya, Egypt, Turkey, Greece, Nigeria, Sierra Leone, Botswana, Kenya, Saudi Arabia, Malaysia, Hong Kong, Korea and Australia. Apart from work related travel, there was much virtual travel via intensive photo reconnaissance and map research for the above and for projects in Algeria, Zimbabwe, Tanzania, the Gulf Emirates, Qatar, Bahrain, Iran, Azerbaijan, Kazakhstan, Singapore, Brunei, Philippines, Indonesia, Russia, Poland, Hungary, Italy, France and Spain.

The work tended to divide broadly as overseas = geology and UK = man-made ground conditions. It was the UK work that involved John in the use of historic air photos (back to the 1920s) and historic topographic mapping at large scales (back to the 1860s) for detecting past industrial land uses and introduced him to early geological mapping. For much of his career the large scale maps (six inch to the mile) of UK and Ireland were unpublished which meant that geologists used hand-coloured manuscript maps (now superseded), held in London (now Keyworth), Edinburgh and Dublin.

John's experience in producing engineering geological and geohazard maps encompasses nineteenth century geological survey maps and the high resolution satellite imagery of the twenty-first century. He has worked with maps from the era of De la Beche, Murchison and Geikie, through archived and commissioned aerial surveys of the 1940s to the end of the twentieth century, and pioneered applications of Landsat imagery in Nigeria (1975) and Botswana (1980) and high resolution satellite imagery in Turkey (2000) and Indonesia (2005).

Annie is the matriarch and active grand-mother of her family. She graciously accepts the takeover by ancient maps of our home. She is very experienced in dealing with people and has worked in publishing and recruitment. In addition to her back office support in the map and geological consulting businesses, she writes poetry and is a skillful proof-reader.

We live in central London on the edge of Notting Hill, close to the Ladbroke Grove Underground Station and the vibrant street market on Portobello Road. Visitors are welcome to our home to view maps and books by prior appointment (Contact Us).

Annie at Display Booth

We exhibit maps at the Annual Festivals of Geology of the Geologists' Association, usually the first week of November, and the AGMs of the Charles Close Society, usually mid-May.


Albert DeLorenzi

In 2009, Albert DeLorenzi started agd Design to provide web design, graphic design and photographic services to clients. Albert brings an extensive background in business development, technology, communications, computing and the Internet in a global marketplace. Today he is primarily focussed on assisting small businesses that need to extend their products and services with the Internet.

He approaches clients with a dialogue about their business and their goals. Establishing mutual trust and understanding their needs and the possibilities lead to the best solution for each client.

The relationship with John started around the question - How can I use the Internet to reach potentential clients with information about my extensive archive of Geological Maps, Books and Illustrations?
Over the last 5 years many clients have asked similar questions in different business areas:

  • Artists
  • Art Galleries
  • Construction Firms
  • Consultants
  • Manufacturers
  • Real Estate
  • non-Profits

Although currently living in the Niagara Region in Canada, his clients are geographically distant, however through the Internet, collaboration flows easily, in a timely manner and cost effectively.
