Dr. Jenny Langer
Background
Dr. Jenny Langer works at the Eau Claire Observatory, in Wisconsin. She has a brother in Oshkosh, Wisconsin who is an interior decorator.
During the events of The Giant Spider Invasion (1975) played by Barbara Hale
Dr. Jenny Langer calls NASA and tells them she has a gamma ray burst reading and the barometer has dropped tremendously. After giving a lecture on stars, Dr. Langer goes to the observatory. Dr. Vance arrives and after assuming he is there to see either her father, brother or husband, she tells him, he is here to see her. She tells him about the readings she had collected and they go to her lab. They look at some readings and they are still not normal. She tells Dr. Vance that due to the radiation levels, anyone living near the meteor crash site would be in great danger and Dr. Vance suggests they try and find the crash site. He asks her if she thinks the Sheriff will help them search for the site using a Geiger Counter. Dr. Langer introduces Dr. Vance to the Sheriff. Perkins walks into Dutch's cafe and greets Dr. Langer and the Sheriff and is introduced to Dr. Vance. He then tells them about what happened to him and Terry the other night. A helicopter pilot tells Dr. Vance that he has identified a highly radioactive area near the Kester place and Dr. Langer asks him if he could take a photo. Dr. Vance and Dr. Langer look at the photo and decide it matches a space warp, or miniature black hole. They go searching for the location of the high radiation. They are still searching for the radiation, when the Giant Spider comes across them and they run away. They go to the Sheriff's office and the Sheriff tells them he just found the remains of Joe Cooper and they tell him there is a fifty foot spider on the loose. The Sheriff shows them some rocks he found near Mr. Cooper and they ask him if they can run some tests on them. They try to figure out how to close the black hole and Dr. Vance comes up with the idea of pumping it full of extra mass. He calls Rider and tells him to send him a machine that can send a charge of neutrons. The device is delivered from NASA and flown inside a helicopter. Dr. Vance tells Dr. Langer that once the device hits the meteorite hole, the spiders will be destroyed, and while walking around they find the skeletal remains of Ev. They call the Sheriff and tell him to bring the spider towards the black hole. The Deputy arrives and tells Dr. Vance and Dr. Langer that the Giant Spider is heading their way. The Deputy tries to keep the Giant Spider away from the black hole until the neutrino gadget is ready, but is killed. The Giant Spider walks towards the black hole and Dr. Vance fires a flare gun and the black hole collapses and the Giant Spider starts to melt. A group of people run towards the melting Giant Spider and Dr. Vance and Dr. Lander hug.
