Lois Rodden was a friend of mine (pen-pal variety, as we never met in person). She used Placidus houses for years and years until she knuckled under to the pressure by her local students in the Los Angeles-San Bernardino area of Southern California and switched to Koch. I could live with that because I could reverse-engineer the charts she supplied to create Placidus houses. Then the late Jayj Jacobs talked her into using equal houses, which was not acceptible to me. Many British users of equal houses add the MC as a point in a chart, but Jayj, following the lead of his father, Moby Dick, was in total disdain of the MC. An equal house chart, without a Midheaven, is very, very difficult to reverse-engineer.
It was later demonstrated that Lois' 6th and final bout with cancer left her so full of medication that some of her later decisions were rather questionably too Neptunian.
Lois was born in Lang, Saskatchewan, Canada. In March, 2008, I took a weekend trip to Regina while I was living and working in North Dakota. I drove through Lang on both the trip up and the trip back.
