2020 will mark the 90th anniversary of the founding of LAI. In 1930, a group of students at Northwestern University in Evanston, Illinois, formed Lambda Alpha -- a fraternity to honour and engage with the teachings of renown economist Richard T. Ely. In the years since, LAI has changed, grown and diversified becoming a leading global, multi-disciplinary, honorary Society for land economics. 30 chapters in the USA, Canada, the United Kingdom, Spain, Mexico, India and Japan constitute an international federation devoted to connecting professionals, sharing knowledge and advancing best practices. ;xNLx;To mark the anniversary, we have begun to assemble a history of LAI using an online timeline. It provides context for the reading of LAI history, but also provides a framework into which additional relevant information can be placed. This new LAI timeline constitutes a significant contribution to the ability of our members to not only learn, but also to contribute to the ongoing development of, the history of our Society.;xNLx;As you will see, the timeline not only highlights significant events in the history of LAI, but provides a means to capture, store and present pictures and stories of the people that have over the years contributed to the making of the Society. For new members especially, the timeline offers an opportunity to learn about the Society in which they have become life-long members and to readily appreciate its values and traditions.;xNLx;The timeline will also allow for the stories of our many Chapters to be told. Parallel timelines can offer individual Chapters the ability to build their own timelines with links to the LAI timeline. All Chapters are invited to participate in the ongoing development of the timeline by assembling a history of the Chapter with dates, names, events and pictures. It is quite easy to build and edit a timeline directly. ;xNLx;I close by sincerely thanking Christine Williams and those who supported this significant effort. It is a most valuable contribution to the betterment of our Society. ;xNLx;Robert McBride, MLAI, P.Eng., RPP;xNLx;LAI International President 2018-2019;xNLx;
